Render the IP address for the "Ubik: Lost contact with sync-site" log

Render the IP address for the "Ubik: Lost contact with sync-site" log
message in the same way that all other IP addresses are (via
afs_inet_ntoa, rather than stripping the buytes out in a manner which
assumes a specific endianism).

Done more as a way to test my understanding of the GIT/GERRIT
technology with a small non-important checkin.
