tipc: ensure all name sequences are released when name table is stopped
As TIPC subscriber server is terminated before name table, no user depends on subscription list of name sequence when name table is stopped. Therefore, all name sequences stored in name table should be released whatever their subscriptions lists are empty or not, otherwise, memory leak might happen.
