yeah it's the re-use of an mbuf that previously passed through pf.  The logging is noise basically though can be painful with a slow (serial) console.  I have a sysctl locally to disable the logging, OpenBSD has removed the printf by now.  I agree that we need to fix these places where it still originates and even if it's for documentation purposes to eventually decide if re-using the mbuf there is really cheaper  to allocating a new one as other people lately found transporting other properties along with the mbuf and re-using that can lead to odd results.
