[Intel-gfx] [PATCH 16/29] drm/i915: Cleanup more of VMA in destroy

[Ben Widawsky]

Remove the VMA from the object's list, and remove the VMA's node from
the allocator. This just helps avoid duplication, since we always want
those two things to occur on destroy, and at least for now, we only do
those two actions on destroy anyway.
