    ZOOKEEPER-3008: Potential NPE in SaslQuorumAuthLearner#authenticate and SaslQuorumAuthServer#authenticate

    @LJ1043041006 found a potential NPE in ZK
    ----
    callee :SecurityUtils#createSaslClient will return null while encounter exception
    ```
    // code placeholder
    catch (Exception e) {
      LOG.error("Exception while trying to create SASL client", e);
      return null;
    }
    ```
    but its caller has no null check just like:
    -----
    and caller ReferenceCountedACLCache#deserialize  call it without null check
    ```
    // code placeholder
    sc = SecurityUtils.createSaslClient();
    if (sc.hasInitialResponse()) {
       responseToken = createSaslToken(new byte[0], sc, learnerLogin);
    }
    ```
