    Revert "mgcp: make sure all endpoints are closed on startup"
    Clearing all endpoints by sending a DLCX on startup has ben found
    to be a bit too offensive. It also will not help against
    inconsitancies that may occour during runtime (e.g. an overheard
    DLCX during regular call teardown).
    This reverts commit b669ea94cb78fd9b56ee8dd9392538151349f8ba.

    mgcp: Make sure endpoint is free on CRCX
    The MSC is aware of the assigned endpoints at all times, so it
    will not assign an occupied endpoint to someone else. However,
    if it has just restarted, there maybe lingering open endpoints.
    This patch introduces a fairly simple soultion. Before a new
    endpoint is seized (CRCX), a DLCX is send in advance. If the
    endpoint was still occupied with a dead connection, it will
    be freed. If it was free anyway, the DLCX will just have no
