That would mean there will be no error reported in case WebSocket is
requested with old qemu, we just won't format the option. But that's
what we do with some other options as well and it should also be added
only if vnc is listening on an open port.

I've added the goto, fixed the upper hunk as well and added info into
the documentation about autoport having no effect on websocket.
Thanks, pushed now,
