drm/xe: Issue GGTT invalidation under lock in ggtt_node_remove
Async work (e.g., GuC queue teardowns) can call ggtt_node_remove, so the
operation must be performed under the GGTT lock to ensure the GGTT
online check remains stable. GGTT insertion and removal are heavyweight
operations (e.g., queue create/destroy), so the additional serialization
cost is negligible compared to ensuring correctness.
