  Log:
  Merge spx_usrreq.c:1.60 from HEAD to RELENG_5:
  
    Clean up return handling for a number of SPX-related routines that
    were derived from more complex TCP versions of the same:
  
    - spx_close(), spx_disconnect(), spx_drop(), and spx_usrclosed() all
      always free's the spxpcb invalidating the argument, so a return
      value is not required to indicate if it has.
    - Annotate that the cb arguments to each of these functions is
      invalidated via a comment.
    - When tearing down a pcb due to sonewconn() having failed, mark the
      cb as NULL; later, when deciding whether to store trace information
      due to SO_DEBUG, check that cb is not NULL before dereferencing or
      a NULL pointer dereference may occur.
