Details:

This issue was one that I ran into when integrating lwIP into the network
stack for the ReactOS project. I had accidentally called tcp_err for a
listening PCB and it caused all sorts of trouble by corrupting random memory.
It took me forever to figure out what was causing the corruption that was
randomly leading to BSODs. I added these assertions so hopefully nobody will
end up in the same boat again.
