scsi: target: tcm_fc: 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_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.
