drm/i915: Unconfuse pre-icl vs. icl+ intel_sagv_{pre,post}_plane_update()
intel_sagv_{pre,post}_plane_update() can accidentally forget to bail out early on pre-icl and proceed down the icl+ codepath at the end of the function. Fortunately it'll bail out before it gets too far due to old_qgv_mask==new_qgv_mask==0 so no real bug here. But lets make the code less confusing anyway.
