Hans de Goede a85722c650 USB: uas: Reduce can_queue to MAX_CMNDS
commit 55ff8cfbc4e12a7d2187df523938cc671fbebdd1 upstream.

The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.

Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.
