    ZOOKEEPER-3951: C Client: Fix compilation with SASL disabled
    
    The `sasl_client` field doesn't exist when configured without SASL.  Use an accessor outside
of the blocks already guarded by `HAVE_CYRUS_SASL_H`.
    
    (Reported by [Parag](https://issues.apache.org/jira/browse/ZOOKEEPER-3951).)
