commit 23ab1cb6591dba7c97b65eb407cd71147bd878b8 upstream.
This was fixed in commit b7dce525c4fc ("drm/xe/queue: fix engine_class bounds check"), but then re-introduced in commit 6f20fc09936e ("drm/xe: Move and export xe_hw_engine lookup.") which should only be simple code movement of the existing function.
