target: Add compare_and_write_post() completion callback fall through
This patch changes target_complete_ok_work() to fall through after calling the se_cmd->transport_complete_callback() -> compare_and_write_post() callback, by keying off the existance of SCF_COMPARE_AND_WRITE_POST. This is necessary because once SCF_COMPARE_AND_WRITE_POST has been set by compare_and_write_post(), the SCSI response needs to be sent via TFO->queue_status().
