glusterd: Add hostname/ip-address along with host's UUID in glusterd log message

Previously when host disconnected from cluster then glusterd logs
identifies host using host's UUID.

Now with this fix, UUID along with host's ip will be present in
glusterd log message when one of the peer disconnected from cluster.
So it will enhancement better readability of user from log file.
