[NET]: Fix neighbour destructor handling.
->neigh_destructor() is killed (not used), replaced with ->neigh_cleanup(), which is called when neighbor entry goes to dead state. At this point everything is still valid: neigh->dev, neigh->parms etc. The device should guarantee that dead neighbor entries (neigh->dead != 0) do not get private part initialized, otherwise nobody will cleanup it. I think this is enough for ipoib which is the only user of this thing. Initialization private part of neighbor entries happens in ipib start_xmit routine, which is not reached when device is down. But it would be better to add explicit test for neigh->dead in any case. Signed-off-by: David S. Miller <davem@davemloft.net>
