Subject: [PATCH] tcm_loop: Enable DIF/DIX modes in SCSI host LLD

This patch updates tcm_loop_driver_probe() to set protection
information using scsi_host_set_prot() and scsi_host_set_guard(),
which currently enabled all modes of DIF/DIX protection, minus
DIX TYPE0.

Also, update tcm_loop_submission_work() to pass struct scsi_cmnd
related protection into target_submit_cmd_map_sgls() during CDB
dispatch.
