[IPSEC]: Move tunnel parsing for IPv4 out of xfrm4_input
This patch moves the tunnel parsing for IPv4 out of xfrm4_input and into xfrm4_tunnel. This change is in line with what IPv6 does and will allow us to merge the two input functions. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
