Log:
  em(4): Always reinit interface when adding/removing VLAN
  
  This partially reverts r361053 since there have been reports
  by users that this breaks some functionality for em(4)
  devices; it seems at first glance that some sort of interface
  restart is required for those cards.
  
  This isn't a proper fix; this unbreaks those users until a proper
  fix is found for their issues.
