After previous patch xfrm4_extract_header is only called from net/xfrm/xfrm_{input,output}.c. Because of IPV6=m linker errors the ipv6 equivalent (xfrm6_extract_header) was already placed in xfrm_inout.h because we can't call functions residing in a module from the core. So do the same for the ipv4 helper and place it next to the ipv6 one.
