config: Fix duplicate error message for nonlocal SocksPorts.

Browse Source 
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.
