[IPSEC]: Move output replay code into xfrm_output
The replay counter is one of only two remaining things in the output code that requires a lock on the xfrm state (the other being the crypto). This patch moves it into the generic xfrm_output so we can remove the lock from the transforms themselves. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
