Problem conclusion

• DFHL2WF has been changed to return the purged response to its
  caller and avoid the system termination path for a disaster
  response in the case of a purge on a lock request. This allows
  the caller of the log append request to report the purged
  response in its own way.
  
  DFHJCP has been changed to return transaction abend AJCU when a
  purged response is returned from an append to DFHLOG.
