logind: tighten assertion in execute_shutdown_or_sleep()

Following commit b498d6ea, I belated realized we should tighten the
assertions as well, to make sure that we're setting `m->action_what` to
represent an action in progress.  (The check for an action in progress is
to compare `m->action_what` to zero)
