target_submit_cmd_map_sgls() is being removed, so convert srpt to the new submission API. srpt 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.
