scsi: target: qla2xxx: Convert to new submission API
target_submit_cmd() is now only for simple drivers that do their
own sync during shutdown and do not use target_stop_session().
tcm_qla2xxx uses target_stop_session() to sync session shutdown with LIO
core, so we use target_init_cmd()/target_submit_prep()/target_submit(),
because target_init_cmd() will detect the target_stop_session() call and
return an error.
