commit 8d2c930735f850e5be6860aeb39b27ac73ca192f upstream.
It incorrectly claimed a resource isn't CPU visible if it's located at
the very end of CPU visible VRAM.
Fixes: a6ff969fe9cb ("drm/amdgpu: fix visible VRAM handling during faults")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3343
