[Intel-gfx] [PATCH] drm/i915/gt: Flush engine->retire on virtual engine cleanup

[Chris Wilson]

For commit dc93c9b69315 ("drm/i915/gt: Schedule request retirement when
signaler idles") we added the intel_engine_init_retire() to the virtual
engine, but since it does not use the common cleanup routine, we need to
also add the intel_engine_fini_retire() to flush the retirement worker
before freeing.

Fixes: dc93c9b69315 ("drm/i915/gt: Schedule request retirement when signaler idles")
