target: Remove legacy device status check from transport_execute_tasks
This patch removes a legacy se_dev_check_online() check from within transport_execute_tasks() that should no longer be necessary as transport_lookup_cmd_lun() is already making this call. Using transport_cmd_check_stop() from transport_execute_tasks() should already be checking per se_cmd context for each descriptor upon active I/O shutdown, so no need to acquire dev->dev_status_lock again while executing se_task submission.
