Re: [Intel-gfx] [PATCH v6 6/6] drm/i915: Use struct vma_resource instead of struct vma_snapshot

There is always a struct vma_resource guaranteed to be alive when we access a corresponding struct vma_snapshot.

So ditch the latter and instead of allocating vma_snapshots, reference the already existning vma_resource.

This requires a couple of extra members in struct vma_resource but that's a small price to pay for the simplification.

v2:

• Fix a missing include and declaration (kernel test robot lkp@intel.com)
