In IPv6 setup, NTP refid is hash result of reference's IPv6 address.
In such case, do not try to intepret the refid to tell if the peer
has a reliable source.
When the NTP service uses peer controller as reference, the alarm
is a reminder to the admin user instead of reporting an issue. This
is a minor alarm.
