[IPSEC]: Add xfrm_input_state helper
This patch adds the xfrm_input_state helper function which returns the current xfrm state being processed on the input path given an sk_buff. This is currently only used by xfrm_input but will be used by ESP upon asynchronous resumption. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
