Details:

Hey,
I've hit an issue in my application where I call netif_remove, and my code
asserted because netif_remove tried to transmit packets, due to TCP
connections being aborted. What do you think about ensuring within lwIP that
this does nott happen? It will probably save a few applications with similar
bugs lurking, and also I don't see any valid reason why packets would need to
be sent to a netif that is being removed.
