drm/amdgpu: Remove kfd eviction fence before release bo (v2)
No need to trigger eviction as the memory mapping will not be used
anymore.
All pt/pd bos share same resv, hence the same shared eviction fence.
Everytime page table is freed, the fence will be signled and that cuases
kfd unexcepted evictions.
v2: squash in 32 bit fix
