When I looked at this a few days ago, it seemed that the fallthrough to
the TUR/INQUIRY case statement was accidental and that the intent was to
quickly complete START_STOP unit (which probably doesn't make much sense
for a RAID device anyway).

See the case statements above for another fast exit scenario.

Sadly I have no way to test this. It just stuck out like a false
positive in Gustavo's fallthrough markup patch.
