glebius a4a6b8f0c4 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.
