kernel - MPSAFE the protocol drain routines

* The ip fragment drain was not MPSAFE at all.  Use a token to protect
  the ipq[] queues.

* The tcp reassembly code was only partially MPSAFE due to being
  per-cpu.  Finish it up.  Use atomic ops for the tcp_reass_qsize
  global.

* Add port assertions in the TCP input and output paths.  If we
  are not in the correct thread we panic, period.

* Code cleanup.
