[PATCH] drm/amdgpu: fix "Revert "drm/amdgpu: move PD/PT bos on LRU again""

[Christian König]

This reverts commit 1156da3d4034957e7927ea68007b981942f5cbd5.

We should review reverts as well cause that one only added an incomplete band
aided to the problem.

Correctly disable bulk moves until we have figured out why they corrupt
the lists.
