    Fix documented kcpreauth minor version
    
    Commit 7b12eb4757f8dd05b79c9b49d4289f0caf1f6eec erroneously changed
    the documented kdcpreauth minor version from 2 to 3.  Only the
    callback version changed in that commit; the interface minor version
    remains at 2 (from commit 83b4ecd20e50ad330cd761977d5dadefe30a785b
    which added the loop method).
