drm: Use a nondestructive mode for output detect when polling (v2)
v2: Julien Cristau pointed out that @nondestructive results in
double-negatives and confusion when trying to interpret the parameter,
so use @force instead. Much easier to type as well. ;-)
And fix the miscompilation of vmgfx reported by Sedat Dilek.
