  Log:
  Fix ng_ksocket(4) operation as a divert socket, which is pretty useful
  and has been broken twice:
  
  - in the beginning of div_output() replace KASSERT with assignment, as
    it was in rev. 1.83. [1] [to be MFCed]
  - refactor changes introduced in rev. 1.100: do not prepend a new tag
    unconditionally. Before doing this check whether we have one. [2]
  
  A small note for all hacking in this area:
  when divert socket is not a real userland, but ng_ksocket(4), we receive
  _the same_ mbufs, that we transmitted to socket. These mbufs have rcvif,
  the tags we've put on them. And we should treat them correctly.
