Subject: [PATCH 4.14 023/106] ipv6: fix typos in __ip6_finish_output()

From: Eric Dumazet <edumazet@...gle.com>

[ Upstream commit 19d36c5f294879949c9d6f57cb61d39cc4c48553 ]

We deal with IPv6 packets, so we need to use IP6CB(skb)->flags and
IP6SKB_REROUTED, instead of IPCB(skb)->flags and IPSKB_REROUTED

Found by code inspection, please double check that fixing this bug
does not surface other bugs.

Fixes: 09ee9dba9611 ("ipv6: Reinject IPv6 packets if IPsec policy matches after SNAT")
