neigh: reorder struct neighbour
It is important to move nud_state outside of the often modified cache
line (because of refcnt), to reduce false sharing in neigh_event_send()
This is a followup of commit 0ed8ddf4045f (neigh: Protect neigh->ha[]
with a seqlock)
This gives a 7% speedup on routing test with IP route cache disabled.
