[PATCH] drm/xe: fix engine_class bounds check again

[Matthew Auld]

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.

Fixes: 6f20fc09936e ("drm/xe: Move and export xe_hw_engine lookup.")
