The majority of those where removed in the commit aed01a68047b
("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2")
But this one was missed because it's working on the resource and not the
BO. Since we also no longer use a fake start address for visible BOs
this will now trigger invalid mapping errors.
v2: also remove the unused variable
