x11: never enable DPMS if we didn't disable it

Browse Source 
Enabling DPMS even though you disabled it globally is pretty unfriendly,
so don't do it. Instead, we only disable DPMS if it was enabled, and
only enable it if we disabled it ourselves.

The other way should never happen (disabling DPMS permanently), unless
mpv crashes during playback.
