fsm.c: Print error message for FSM with allstate_action but no events

As suggested by Vadim while reviewing a related fix for ipa_keepalive.c
in libosmo-abis (see https://gerrit.osmocom.org/#/c/libosmo-abis/+/13540/),
it makes sense to print an error message if anyone registers a FSM
that specifies an allstate_action callback but at the same time no
events that would ever end up in that callback.
