Christoph Hellwig 1e6f241604 scsi: don't allow setting of queue_depth bigger than can_queue 
We won't ever queue more commands than the host allows.  Instead of
letting drivers either reject or ignore this case handle it in
common code.  Note that various driver use internal constant or
variables that are assigned to both shost->can_queue and checked
in ->change_queue_depth - I did remove those checks as well.
