SDEV_QUIESCE was set for all lu's scsi_devices by ufs shutdown, and at that time the audio driver was waiting on blk_mq_submit_bio holding a mutex_lock while reading the fw binary. After that, a deadlock issue occurred while audio driver shutdown was waiting for mutex_unlock of blk_mq_submit_bio. To solve this, set SDEV_OFFLINE for all lus except wlun, so that any i/o that comes down after a ufs shutdown will return an error.
