Fix to non-rd variance partition selection.

Only test for using golden as reference for variance partition
selection if it is used as a reference for that frame.

For temporal layers, golden may not be a reference on a given frame,
even though it was for some previous frame. If it is not a reference
for current frame, don't check/use it for partition selection.
