drm_gem_object_unreference() now expects obj->dev->struct_mutex to be held. Use the newly-introduced drm_gem_object_unreference_unlocked() which handles locking for us.
If we don't do this drm_gem_object_unreference() will get noisy about struct_mutex not being held every time we call the SET_TILING ioctl.
