Christian König 52f650963d drm/amdgpu: fix check in amdgpu_hmm_invalidate_gfx
For a short moment during alloc/free the userptr BO is not part of his VM,
so bo->vm_bo can be NULL.

Keep a reference to the VM root PD as parent of the userptr BO so that
we can always use that to wait for all submissions of the VM instead of
only the one involving the userptr BO.
