Patch 1 - 4 moves validations and skb allocation in neigh_get()
as prep for patch 5, which converts RTM_GETNEIGH to RCU.

Patch 6 & 7 converts RTM_GETNEIGHTBL and RTM_SETNEIGHTBL to RCU,
which requires almost nothing.


Changes:
  v2:
    * Patch 1 & 2 : Fix ERR_PTR(0) paths

  v1: https://lore.kernel.org/netdev/20250416004253.20103-1-kuniyu@amazon.com/
