  pf: Do not flush on reload
  
  pfctl only takes the last '-F' argument into account, so this never did what
  was intended.
  
  Moreover, there is no reason to flush rules before reloading, because pf keeps
  track of the rule which created a given state. That means that existing
  connections will keep being processed according to the rule which originally
  created them. Simply reloading the (new) rules suffices. The new rules will
  apply to new connections.
