wayland: initalize display_fd as -1

Browse Source 
In the event of a failed wayland initalization, the display_fd is
actually 0 instead of -1 which would correctly indicate it doesn't
exist. Also move the fd check inside vo_wayland_dispatch_events since
that function shouldn't ever do anything if we don't actually have a
display fd.
