drm/amd/display: Avoid updating surface with the same surface under MPO
[ Upstream commit 1a38ded4bc8ac09fd029ec656b1e2c98cc0d238c ]
[Why & How]
Although it's dummy updates of surface update for committing stream
updates, we should not have dummy_updates[j].surface all indicating
to the same surface under multiple surfaces case. Otherwise,
copy_surface_update_to_plane() in update_planes_and_stream_state()
will update to the same surface only.
