5.10-stable review patch. If anyone has any objections, please let me know.

From: Ian Forbes <ian.forbes@xxxxxxxxxxxx>
[ 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")
