tipc: Optimize re-initialization of configuration service
Streamlines the job of re-initializing TIPC's configuration service when a node's network address is first assigned. Rather than destroying the configuration server port and then recreating it, TIPC now simply withdraws the existing {0,<0.0.0>} name publication and creates a new {0,<Z.C.N>} name publication that identifies the node's network address to interested subscribers.
