Partitions with no integrity should not report any ECC related errors.
In order to be on the safe side, we filter error responses in that case since they may trigger (unwanted) alerts.

This allows us to disable integrity on the VENDOR_TEST partition in Earlgrey discrete without having to change the internal behavior of the OTP wrapper.

@meisnere @arnonsha with this change, no further changes are required on the closed source side. The only thing that needs to be done is remapping of ReadRaw -> Read and WriteRaw -> Write.
