Dropping to untagged mode when ramping down a queue due to QUEUE FULL

- nothing in the midlayer or drivers ever moves back to tagged mode

- 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.
