[IPSEC]: Only set neighbour on top xfrm dst
The neighbour field is only used by dst_confirm which only ever happens on the top-most xfrm dst. So it's a waste to duplicate for every other xfrm dst. This patch moves its setting out of the loop so that only the top one gets set. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
