  Log:
  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.
