    heimdal: fix endless loop for specific KDC error code
    
    When sending a Kerberos request, if at least one of the available
    KDCs repeatedly replies with an error response of
    KRB5KDC_ERR_SVC_UNAVAILABLE, and all other KDCs, if there are any,
    do not reply at all or cannot be contacted, then the code repeatedly
    retries to send the request in an endless loop.
    
    This is fixed in upstream (post 1.5 branch) heimdal but the code
    there is vastly refactored, so this is an independent fix to the issue.
