xfrm: Introduce xfrm_input_afinfo to access the the callbacks properly
IPv6 can be build as a module, so we need mechanism to access the address family dependent callback functions properly. Therefore we introduce xfrm_input_afinfo, similar to that what we have for the address family dependent part of policies and states. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
