c2ea0911 introduced a crasher for IKEv1. When pluto replace IKE SA and delete
itself.

I think Tuomo also noticed this crasher. He mentioned that he is working on it
on IRC.
Here is a simple fix for it. Possibly there is a better way to clean up freeing
st_requested_ca.
leak detect was not enabled when I tried. It seems to have disappeared again.
I wonder if the c2ea0911 was only tested for IKEv2? IKEv2 does not seems to
have this issue. Or possibly interoperating with other implemenations?

PS: in the testcase you could test it in ikev2-20-ikesa-replace
change ikev2=never on road.conf and east.conf.
