Base the number of outstanding requests the driver will keep track of on the
available resources instead of being hard-coded.

It is possible for the target code to change the loop_id or s_id of a
target session in reaction to an FC fabric change. However, the
session structures are stored in tables that are indexed by these two
keys, and if we just change the session structure but leave the
pointers to it in the old places in the table, havoc can ensue. For
example, a new session might come along that should go in the old slot
in the table and overwrite the old session pointer.
To handle this, add a new tgt_ops->update_sess() method that also
updates the "by loop_id" and "by s_id" lookup tables when a session
changes, so that the keys where a session pointer is stored in these
tables always matches the keys in the session structure itself.

The only place that sets qla_tgt_sess.tearing_down calls
target_splice_sess_cmd_list() immediately afterwards, without dropping
the lock it holds. That function sets se_session.sess_tearing_down,
so we can get rid of the qla_target-specific flag, and in the one
place that looks at the qla_tgt_sess.tearing_down flag just test
se_session.sess_tearing_down instead.

Defer the whole tcm_qla2xxx_handle_data call instead of just the error
path to the qla2xxx-internal workqueue. Also remove the useless lock around
the CMD_T_ABORTED check.

Add LLD target mode for >= 24xx series HW. This code was originally based on
external qla2x00t module based on 8.02.01-k4, and has been refactored to
push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c.
The implementation uses internal workqueues for I/O context submission
into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for
external interaction to allow qla2xxx LDD to function without direct
target-core dependencies:
It also enables qla_target.c usage within existing qla2xxx LLD code.
This includes:
*) Addition of target mode specific members to existing data
structures in qla_def.h and struct qla_hw_data->tgt_ops using
qla_target.h:struct qla_tgt_func_tmpl
*) Addition of struct qla_tgt_func_tmpl and direct calls into
qla_target.c logic w/ qlt_* prefixed functions.
*) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and
qla2x00_issue_marker() for handling request/response queue processing
for target mode operation
*) Addition of various qla_tgt_mode_enabled() logic checks in
qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(),
qla2x00_abort_isp(), qla24xx_modify_vp_config(), and
qla2x00_vp_abort_isp().
By default the new qlini_mode module parameter is setting initiator-mode
to 'enabled' in order for 'modprobe qla2xxx' to continue to function as
expected in initiator only mode. Enabling target-mode operation will
currently require a:
modprobe qla2xxx qlini_mode="disabled"
in order to explictly disabled initiator mode and allow target-mode
to be enabled via tcm_qla2xxx configfs fabric callers.
(nab: Convert to qlini_mode='enabled' by default in qla_target.c)
(joern: Remove loop_id from qla_tgt_make_local_sess() arguments +
Remove unused s_id + fix s_id endianness bug +
simplify qla_tgt_abort_work)
(gerard: fix section __exit mismatch in qla_tgt_exit)
(arun: Capture ATIO queue during firmware dump + Send SCR in target mode +
Target mode review comments)
(roland: Don't create duplicate target sessions to address tearing down
ACLs with IO in flight + Add missing call to qlt_fc_port_deleted
call during qla2x00_schedule_rport_del timeout)
