We will allocate per-netns neigh_table in net->neigh_tables[].
Let's replace &arp_tbl with arp_table(net) and remove extern
definition for arp_tbl.
Three notes:
1. mlx5e_rep_netevent_event() and nfp_tun_neigh_event_handler()
have code assuming neigh_table other than &arp_tbl and
&nb_tbl, and the part is removed as it will be false once
per-netns table is allocated.
2. prestera and rocker uses init_net because they set
dev->netns_immutable to true.
3. mlx5e_tc_update_neigh_used_value() dereferences nhe->neigh_dev
in trace_mlx5e_tc_update_neigh_used_value().

v2: Add note about mlx5e_tc_update_neigh_used_value()Seems like this is not a bisectable patch set. References for arp_tbl and nd_tbl need to be fixed up before switching to per network namespace tables.
