Log:
  MFC r325850: pfctl: teach route-to to deal with interfaces with multiple addresses
  
  The route_host parsing code set the interface name, but only for the first
  node_host in the list. If that one happened to be the inet6 address and the
  rule wanted an inet address it'd get removed by remove_invalid_hosts() later
  on, and we'd have no interface name.
  
  We must set the interface name for all node_host entries in the list, not just
  the first one.
