drm/nouveau/kms/nv50: skip core channel cursor update on position-only changes

commit e6db95799b1b870aae15682a6d0898df9e9dfb38 upstream.

The DRM core used to only call prepare_fb/cleanup_fb() when a plane's
framebuffer changed, which achieved the desired effect.

It's apparently now up to the driver to decide on its own.
