mgcp: make sure all endpoints are closed on startup
If the MSC is crashing and restarting, it may leave some endpoints open. The endpoints can not be re-used until they are deleted (DLCX). This patch sends a DLCX to all possible endpoints (usually this is in a countable range) in order to clear possible open endpoints from a previous run
