Mike Christie Feb. 27, 2021, 4:59 p.m.
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.
