Eric Dumazet a073350c5f neighbour: remove neigh_cleanup() method
[ Upstream commit f394722fb0d0f701119368959d7cd0ecbc46363a ]

neigh_cleanup() has not been used for seven years, and was a wrong design.

Messing with shared pointer in bond_neigh_init() without proper
memory barriers would at least trigger syzbot complains eventually.

It is time to remove this stuff.
