iser-target: Move INIT_WORK setup into isert_create_device_ib_res
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.
