target_submit_cmd is now only for simple drivers that do their
own sync during shutdown and do not use target_stop_session,
tcm_fc 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 now detect the target_stop_session call
and return an error.
