Fix bug #8170: Crash when client disconnects unexpectedly

Browse Source 
When the socket does not exist anymore, we should not try to access it. In
trying to do so, std::map will create a new shared_ptr but this pointer
doesn't point at anything. To prevent this, we explicitly check whether
the socket is available.
