[krbdev.mit.edu #5622] kpropd fails to respond with an error indication if kdb5_util fails

[Ken Raeburn via RT]

(See recent messages on kerberos at mit from Le Trung Kien.)

If various errors happen while receiving the data from kprop, kpropd  
can return a krb5_error message to kprop describing the problem.   
However, if "kdb5_util load" fails, the kpropd process simply exits  
without sending anything back, causing kpropd to report "software  
caused connection abort" or some such.  It should instead send back a  
message indicating that kdb5_util failed.
