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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: stable@vger.kernel.org [4.10+]
