drm/virtio: Use appropriate atomic state in virtio_gpu_plane_cleanup_fb()

[ Upstream commit 4656b3a2 ]

Make virtio_gpu_plane_cleanup_fb() to clean the state which DRM core
wants to clean up and not the current plane's state. Normally the older
atomic state is cleaned up, but the newer state could also be cleaned up
in case of aborted commits.
