fou: Remove IPPROTO_UDPLITE check in gue_err() and gue6_err().
UDP-Lite has been removed, and its error handler is no
longer found in either inet_protos[IPPROTO_UDPLITE] or
inet6_protos[IPPROTO_UDPLITE].
The recursion fixed by the protocol check in gue_err()
and gue6_err() no longer occurs with UDP-Lite.
Let's remove the checks.
