Crypto devices may sometimes have multiple additional prober matches,
however just like RAID, there's no danger of activating the wrong one
since special help is needed to activate the block device before it
can be used.
Thus modify blkid_do_safeprobe() to break out of the loop when a
crypto device is detected, as it does already for RAID.
