fsm: do not terminate child FSMs early

The function _osmo_fsm_inst_term() terminates all child FSMs befor
it calls fi->fsm_cleanup(). This prevnts the cleanup callback to
perform last actions on the child FSMs (e.g.
osmo_fsm_inst_unlink_parent()).

move the function call to  _osmo_fsm_inst_term_children() below the
call to fi->fsm->cleanup().
