Subject: [PATCH 5.13 029/223] drm/vmwgfx: Fix a bad merge in otable batch takedown

From: Zack Rusin <zackr@...are.com>

[ Upstream commit 34bd46bcf3de72cbffcdc42d3fa67e543d1c869b ]

Change
2ef4fb92363c ("drm/vmwgfx: Make sure bo's are unpinned before putting them back")
caused a conflict in one of the drm trees and the merge commit
68a32ba14177 ("Merge tag 'drm-next-2021-04-28' of git://anongit.freedesktop.org/drm/drm")
accidently re-added code that the original change was removing.
Fixed by removing the incorrect buffer unpin - it has already been unpinned
two lines above.

Fixes: 68a32ba14177 ("Merge tag 'drm-next-2021-04-28' of git://anongit.freedesktop.org/drm/drm")
