  The host-id/interface-id can have a specific value and is properly
  masked out when adding a prefix route through the "route" command.
  However, when deleting the route, simply changing the command keyword
  from "add" to "delete" does not work. The failoure is observed in
  both IPv4 and IPv6 route insertion. The patch makes the route command
  behavior consistent between the "add" and the "delete" operation.
