fsm: add flag to ensure osmo_fsm_inst_term() happens only once
To prevent re-entering osmo_fsm_inst_term() twice for the same osmo_fsm_inst,
add flag osmo_fsm_inst.proc.terminating. osmo_fsm_inst_term() sets this to
true, or exits if it already is true.
Update fsm_dealloc_test.err for illustration. It is not relevant for unit
testing yet, just showing the difference.
