xfrm: state: remove extract_input indirection from xfrm_state_afinfo
In order to keep CONFIG_IPV6=m working, xfrm6_extract_header needs to be duplicated. It will be removed again in a followup change when the remaining caller is moved to net/xfrm as well. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
