Have you tested this change works as you expect?

I would expect you have to read the bytes off the network to get them out of the way before trying to parse the next MQTT packet. This change will leave the bytes of the too-long message in place, so the next attempt to parse an MQTT packet will start with those bytes and we will be out of sync.
