ipv4: Fix neigh lookup keying over loopback/point-to-point devices. We were using a special key "0" for all loopback and point-to-point device neigh lookups under ipv4, but we wouldn't use that special key for the neigh creation. So basically we'd make a new neigh at each and every lookup :-) This special case to use only one neigh for these device types is of dubious value, so just remove it entirely.
