Subject: [PATCH] Don't try to quit multiple times (#1392)

Calls to CIRCSock::Quit() eventually result in the object's destructor
being called, which itself calls CIRCSock::Quit() again. Avoid sending
multiple quit messages to the remote server by checking if the
underlying socket is already marked for closing.
