    config: Fix duplicate error message for nonlocal SocksPorts.
    
    If `validate_only` is true, then just validate the configuration without warning
    about it.  This way, we only emit warnings when the listener is actually opened.
    (Otherwise, every time we parse the config we will might re-warn and we would
    need to keep state; whereas the listeners are only opened once.)
    
     * FIXES #4019.
