drm/i915: Pass the correct crtc state to .update_plane()
commit 9f6151c9039084e18c118831779a99ac8f29e39c upstream.
Pass the current crtc state, not the old crtc state, to the
.update_plane() hook.
Noticed on BSW when PRIMSIZE was getting programmed to a stale value
which produced utter garbage on screen eg. wwhen going from 1920x1080
to 1024x768.
