drm/vmwgfx: Fix overlay when using Screen Targets

Browse source 
[ Upstream commit cb372a505a994cb39aa75acfb8b3bcf94787cf94 ]

This code was never updated to support Screen Targets.
Fixes a bug where Xv playback displays a green screen instead of actual
video contents when 3D acceleration is disabled in the guest.

Fixes: c8261a961ece ("vmwgfx: Major KMS refactoring / cleanup in preparation of screen targets")
