Subject: [PATCH net-next v2 06/10] ipv6: pass full cork into __ip6_append_data()

Convert a struct inet_cork argument in __ip6_append_data() to struct
inet_cork_full. As one struct contains another inet_cork is still can
be accessed via ->base field. It's a preparation patch making further
changes a bit cleaner.
