Merge r183662 and r183663 from head to stable/7:

  Don't pass curthread to sbreserve_locked() in tcp_do_segment(), as the
  netisr or ithread's socket buffer size limit is not the right limit to
  use.  Instead, pass NULL as the other two calls to sbreserve_locked()
  in the TCP input path (tcp_mss()) do.

  In practice, this is a no-op, as ithreads and the netisr run without a
  process limit on socket buffer use, and a NULL thread pointer leads to
  not using the process's limit, if any.  However, if tcp_input() is
  called in other contexts that do have limits, this may prevent the
  incorrect limit from being used.

  Rewrite sbreserve_locked()'s comment on NULL thread pointers, eliminating
  an XXXRW about the comment being stale.
