scsi: target: srpt: Convert to new submission API

Browse Source 
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.
