[PATCH] drm/xe: Fix unexpected backmerge results

[Thomas Hellström]

The recent backmerge from drm-next to drm-xe-next brought with it
some silent unexpected results. One code snippet was added twice
and a partial revert was partially reverted. Fix that up to
reinstate the code as it was before the backmerge.

Fixes: 79790b6818e9 ("Merge drm/drm-next into drm-xe-next")
