[ Upstream commit 35e22e49a5d6a741ebe7f2dd280b2052c3003ef7 ]

In tipc_server_stop(), we iterate over the connections with limiting factor as server's idr_in_use. We ignore the fact that this variable is decremented in tipc_close_conn(), leading to premature exit.

In this commit, we iterate until the we have no connections left.
