Subject: [PATCH 08/39] drm/vkms: Convert vkms_crtc_atomic_check() to use
 new plane state

The vkms_crtc_atomic_check() function calls the deprecated
drm_atomic_get_existing_plane_state() helper for its internal mode
checking logic.

During atomic_check, the existing state is the new state and
drm_atomic_get_existing_plane_state() can thus be replaced by
drm_atomic_get_new_plane_state().
