There's really no value in the WARN stack trace etc., the reason for this happening isn't directly related to the calling function anyway. Also, syzbot has been observing it constantly, and there's no way we can resolve it there - those systems are just slow. Instead print an error message (once) and add a comment about what really causes this message.
