Fix potential memory leak when attestation delegate is set

[yufengwangca]

1. When we call into the Java VM from native code, so there is no Java VM do the garbage collection to release the reference object

 jclass deviceAttestationDelegateCls = nullptr;
        JniReferences::GetInstance().GetClassRef(env, "chip/devicecontroller/DeviceAttestationDelegate",
                                                 deviceAttestationDelegateCls);

We need to manually release the reference object deviceAttestationDelegateCls when we're done with it.

2. Based on the Java interface design, attestationInfo should be set to null if errorCode is 0

   * @param devicePtr Handle of device being commissioned
   * @param attestationInfo Attestation information for the device, null is errorCode is 0.
   * @param errorCode Error code on attestation failure. 0 if succeed.
   */
  void onDeviceAttestationCompleted(long devicePtr, AttestationInfo attestationInfo, int errorCode);
