[Intel-gfx] [PATCH driver/intel] sna/cursor: Make sure hw cursors are disabled before disabling secondary planes

[Egbert Eich]

When the hw cursors are not disabled before the cursor planes get disabled
we may lose the cursor later on. Thus make sure the cursors are disabled
before the cursor planes are.
