Repost [PATCH 2 of 3] ipoib: move destructor to struct neigh_parms

[Michael S. Tsirkin]

Sorry about reposting: the message didnt seem to make it to netdev.

---

Move destructor from neigh_ops (which is shared between devices)
to neigh_parms which is not, so that multiple drivers can set
it safely.
