kernel - Fix numerous MP issues with sockbuf's and ssb_flags part 1/2

* Use atomic ops for ssb_flags handling

* Use atomic_cmpset_int() to interlock SSB_LOCK with SSB_WANT, and
  SSB_WAIT with SSB_WAKEUP.

  Note in particular that WAIT/WAKEUP assumes the client side of the
  socket is single threaded via an appropriate lock.  This needs more
  work.
