Subject: iser-target: Move INIT_WORK setup into isert_create_device_ib_res

commit 2853c2b6671509591be09213954d7249ca6ff224 upstream.

This patch moves INIT_WORK setup for cq_desc->cq_[rx,tx]_work into
isert_create_device_ib_res(), instead of being done each callback
invocation in isert_cq_[rx,tx]_callback().

This also fixes a 'INFO: trying to register non-static key' warning
when cancel_work_sync() is called before INIT_WORK has setup the
struct work_struct.
