This happens when the amdgpu_bo_release_notify running

check the buffer funcs enablement before calling the fill
buffer memory.

- Apply it only for GEM buffers and since GEM buffers are only
allocated/freed while the driver is loaded we never run into
the issue to clear with buffer funcs disabled.

Cc: <stable@xxxxxxxxxxxxxxx> # 6.10+
I think the stable tag really won't be needed and could be dropped when
this is committed. This will presumably go into a -fixes PR for 6.10.
