  Log:
  MFC: 1.122->1.223 Set up `ia' properly for dummynet packets to avoid
  dereferencing an unitialised pointer.
  
  This change includes some over-defensive checks not present in the
  patch applied to -current; we set `ia' to NULL at the start of
  ip_output(), check that the dummynet route is non-NULL, and that
  `ia' is non-NULL before it is dereferenced. This are just safety
  measures which can be removed when the per-ifaddr stats code has
  had a bit more testing time in -current.
