ntp: don't accept packets with unexpected authentication

If authentication is not enabled in configuration, responses are not
expected to be authenticated. Handle such responses as having failed
authentication.

A case where this could happen is a misconfigured symmetric association
where only one peer has specified the other with a key. Before this
change synchronization would work in one direction and used packets
with an asymmetric length.
