dm crypt: fix crash by adding missing check for auth key size
If dm-crypt uses authenticated mode with separate MAC, there are two
concatenated part of the key structure - key(s) for encryption and
authentication key.
Add a missing check for authenticated key length. If this key length is
smaller than actually provided key, dm-crypt now properly fails instead
of crashing.
