tipc: Optimization to multicast name lookup algorithm
This patch simplifies and speeds up TIPC's algorithm for identifying on-node and off-node destinations that overlap a multicast name sequence range. Rather than traversing the list of all known name publications within the cluster, it now traverses the (potentially much shorter) list of name publications made by the node itself, and determines if any off-node destinations exist by comparing the sizes of the two lists. (Since the node list must be a subset of the cluster list, a difference in sizes means that at least one off-node destination must exist.)
