 In r21175 (on the mskrb branch, merged in r21690) the result codes for
 password quality and other errors were accidentally reversed.  Fix
 them so that password quality errors generate a "soft" failure and
 other errors generate a "hard" failure, as Heimdal and Microsoft do.
 Also recognize KADM5_PASS_Q_GENERIC (added in 1.9) as a password
 quality error.
