Ticket History #6480: Do not return PREAUTH_FAILED on unknown preauth

If the KDC receives unknown pre-authentication data then ignore it.
Do not get into a case where PREAUTH_FAILED is returned because of
unknown pre-authentication. The main AS loop will cause
PREAUTH_REQUIRED to be returned if the preauth_required flag is set
and no valid preauth is found.
