The next patch splits target_submit_cmd_map_sgls so the initialization
and submission part can be called at different times. If the init part
fails we can reference the t_task_cdb early in some of the logging
and tracing code. This moves it to transport_init_se_cmd so we don't
hit NULL pointer crashes.
