Subject: [PATCH 1422/4131] drm/amdgpu: Remove KFD PT BOs from TTM LRU list
PD/PT reservation removed PD BO from TTM LRU list but did not remove
PT BOs since they share its reservation object. TTM eviction later
considers the PT BOs on the LRU list and WARNs that they are pinned.
Remove PT BOs from LRU list when KFD requests a BO to be mapped.
