[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.
