rspro_client_fsm: Fix handling of IPA keepalive

We cannot rely on the implicit IPA keepalive FSM termination, as that
somehow gets the termination order wrong and we end up accessing free'd
memory.

Let's handle the termination explicitly:  We register a callback with
the IPA keepalive FSM, and once that callback gets hit, we ask the
core to *not* terminate the FSM implicitly.  We are anyway terminating
it explicitly in st_reestablish_onenter().
