ip diverting causes panic with 1.3-*

Hi!

I got panics when I tried to set up a nat gateway with DragonFly (more
concretely, with DragonFlyPreview and DragonFlyStable, within a few
days).

Here goes the debug output obtained with DragonFlyPreview (what I see
with DragonFlyStable upon panic seems to be the same).
