[Intel-gfx] [PATCH] drm/i915/selftests: Fixup a couple of missing serialisation with vma

In commit 70d6894d1456 ("drm/i915: Serialize against vma moves")
I managed to miss a couple of i915_vma_move_to_active() that had not
serialised against an async vma pinning. Add the missing
i915_request_await.
