Noticed while reviewing the fence locking in the radeon pageflip handler. v2: Instead of grabbing the bdev->fence_lock in object_transfer just move the single callsite of that function a few lines, so that it is protected by the fence_lock. Suggested by Jerome Glisse. v3: Fix typo in commit message.
