ublk: Limit dev_id/ub_number values
The dev_id/ub_number is used for the ublk dev's char device's minor
number so it has to fit into MINORMASK. This patch adds checks to prevent
userspace from passing a number that's too large and limits what can be
allocated by the ublk_index_idr for the case where userspace has the
kernel allocate the dev_id/ub_number.
