Fix legacy cursor updates on xe by enforcing wait between updating registers and unpin. In comparison with previous version, there was a small bug in the atomic unpin path. In intel_plane_cleanup_fb we tried to deference plane_state after calling vblank schedule. Remove plane from atomic state immediately after scheduling to prevent this issue. It's unsafe to deference plane_state as soon as schedule occured.
