drm: Fixup locking WARN_ON mistake around gem_object_free_unlocked
Embarrassingly while fixing up the old paths for i915 I managed to
misplace a locking check for the new _unlocked paths. That's what I
get for not retesting on radeon.
Fixes: 9f0ba539d13a ("drm/gem: support BO freeing without dev->struct_mutex")
