autofs-5.0.6 - fix paged query more results check
    
    When getting paged results from an LDAP server the server returns an
    opaque cookie (of type berval) that is used to retrieve the next page.
    The criteria for deciding if there are more pages is that the berval
    value is non-null and has a non-zero length.
    
    To determine if the berval value has non-zero length autofs checks the
    strlen() of the value but on ppc64 and s390x this can return 0 even if
    the value has non-zero length causing a premature termination of the
    query.
    
    Fix this by also checking the berval length field.
    Also make sure we free the opaque cookie when the query is finished.
