[PATCH 3/4] rust: drm: gem: s/into_gem_obj()/as_gem_obj()/

[Lyude Paul <lyude@redhat.com>]

There's a few changes here:
* The rename, of course (this should also let us drop the clippy annotation
  here)
* Return *mut bindings::drm_gem_object instead of
  &Opaque<bindings::drm_gem_object> - the latter doesn't really have any
  benefit and just results in conversion from the rust type to the C type
  having to be more verbose than necessary.
