Yue Haibing c956910d5a tipc: Remove unused function declarations
Commit d50ccc2d39 ("tipc: add 128-bit node identifier") declared but never
implemented tipc_node_id2hash().
Also commit 5c216e1d28 ("tipc: Allow run-time alteration of default link settings")
never implemented tipc_media_set_priority() and tipc_media_set_window(),
commit cad2929dc4 ("tipc: update a binding service via broadcast") only declared
tipc_named_bcast().

Since commit be07f05639 ("tipc: simplify the finalize work queue")
tipc_sched_net_finalize() is removed and declaration is unused.
