[PATCH] drm/amdgpu: remove invalid resource->start check

[Christian König]

The majority of those where removed in the patch 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.
