iscsi-target: Prepare login code for multi-plexing support
This patch prepares the iscsi-target login code for multi-plexing support. This includes: - Adding iscsi_tpg_np->tpg_np_kref + iscsit_login_kref_put() for handling callback of iscsi_tpg_np->tpg_np_comp - Adding kref_put() in iscsit_deaccess_np() - Adding kref_put() and wait_for_completion() in iscsit_reset_np_thread() - Refactor login failure path release logic into iscsi_target_login_sess_out() - Update __iscsi_target_login_thread() to handle iscsi_post_login_handler() asynchronous completion - Add shutdown parameter for iscsit_clear_tpg_np_login_thread*() v3 changes: - Convert iscsi_portal_group->np_login_lock to ->np_login_sem - Add LOGIN_FLAGS definitions v2 changes: - Remove duplicate call to iscsi_post_login_handler() in __iscsi_target_login_thread() - Drop unused iscsi_np->np_login_tpg Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
