In the case of per-connection keying, the connection is closed only when
the application stops running. But here the case is different. The
application has still packets to send, but the SA has run out of
bytes(Note: we considered the case when SA has life time in byte counts)
and has to be renegotiated. Hence the H1(sender) can't wait till the
connection closes for sending a delete payload to H2.
