event(3) says event_del() has no effect if an event “has already
executed or has never been added”. It describes evtimer_del() and
signal_del() as abbreviations for the same event API, so checking
whether a timer or signal event is pending immediately before deleting
it is unnecessary.

This patch removes those checks from cleanup paths in ldapd, radiusd,
and vmd.

These are mechanical cleanups; event scheduling and callback behavior
are unchanged.

Comments/OK?
