Ugh.  So we're relying on the fact that no one else is sticking
something in the ->ha member where we stash the ipoib_neigh.

Basically we're getting lucky that this works at all.

As you said in your other mail, it seems like a more fundamental
reorganization of this neighbour destructor stuff is required.
