drm/nouveau/kms/nv50: fix source-rect-only plane updates
This "optimisation" (which was originally meant to skip updating cursor
settings in the core channel on position-only updates) turned out to be
pointless in the final design of the code before it was merged.
Remove it completely, as it breaks other cases.
