This patch fixes the following issues:

- Routing messages are not generated when adding and removing
  interface address aliases.
- Loopback route installed for an interface address alias is
  not deleted from the routing table when that address alias
  is removed from the associated interface.
- Function in_ifscrub() is called extraneously.
