  -----------
  clusterer: Improve handling for NULL sip_addr

A NULL sip_addr field should result in a false sip_addr matching with
any other node.

This prevents unnecessary error logs in simple federated usrloc setups
(no HA) where we don't necessarily need to fill in a "sip_addr" field
for each node.
