drm/vmwgfx: Fix Legacy Display Unit
commit782e5e7925
upstream. Legacy DU was broken by the referenced fixes commit because the placement and the busy_placement no longer pointed to the same object. This was later fixed indirectly by commita78a8da51b
("drm/ttm: replace busy placement with flags v6") in v6.9. Fixes:39985eea5a
