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.
