[mutter: 184/209] Don't call IceCloseConnection() behind libSM's back

    Don't call IceCloseConnection() behind libSM's back
    
    The ICE connection is opened by libSM; we can't just close it when
    we get an IOError on the ICE connection; instead call SmcCloseConnection()
    and mark the connection as closed. This will prevent a segfault if we
    exit out of the metacity main loop and get to meta_finalize().
