scsi: never drop to untagged mode during queue ramp down
Dropping to untagged mode when ramping down a queue due to QUEUE FULL
events has two problems:
- nothing in the midlayer or drivers ever moves back to tagged mode
during queue ramp up.
- cmd_per_lun isn't the untagged queue depth for many modern drivers
that can handle multiple untagged commands, and this is the only
place in the midlayer assuming that.
