Bo, it's not really what we want.  I think we simply need to move
forward with the queue state machine, and use that to check if we have
a blk-mq queue allocated for the queue.  If not we can simply skip it
later on.

So I'd say I'll send the crash fix in blk-mq to Jens ASAP, and you'll
look into the queue state machine for 4.9?
