When using cpu to update page tables, vm update fences are unused.
Install stub fence into these fence pointers instead of NULL
to avoid NULL dereference when calling dma_fence_wait() on them.

This patch here should probably not have been back ported.
Why was that done anyway? The upstream commit doesn't have a CC stable and
this is only a bug fix for a new feature not present on older kernels.
depending on when the amdgpu feature landed.
Both the feature and the bug fix landed in 6.5.
The bug fix should have never been backported to any older kernel at all as far as I can see.
Regards,
Christian.
