tipc: Ensure network address change doesn't impact configuration service
Enhances command validation done by TIPC's configuration service so that it works properly even if the node's network address is changed in mid-operation. The default node address of <0.0.0> is now recognized as an alias for "this node" even after a new network address has been assigned.
