drm/xe: add lockdep annotation for xe_device_mem_access_put()

The main motivation is with d3cold which will make the suspend and
resume callbacks even more scary, but is useful regardless. We already
have the needed annotation on the acquire side with
xe_device_mem_access_get(), and by adding the annotation on the release
side we should have a lot more confidence that our locking hierarchy is
correct.

v2:
  - Move the annotation into both callbacks for better symmetry. Also
    don't hold over the entire mem_access_get(); we only need to lockep
    to understand what is being held upon entering mem_access_get(), and
    how that matches up with locks in the callbacks.
