[Swan-dev] core in ikev2-13-ah

[D. Hugh Redelmeier]

I'm testing some changes.  I got a core on east.  It doesn't look related 
to my changes.

In start_dh_v2:

	DBG(DBG_CONTROLMORE,
            DBG_log("offloading IKEv2 SKEYSEED using prf=%s integ=%s cipherkey=%s",
                    st->st_oakley.ta_prf->common.fqn,
                    st->st_oakley.ta_integ->common.fqn,
		    st->st_oakley.ta_encrypt->common.fqn));

This segfaults because 
	st->st_oakley.ta_encrypt
is NULL.
