Fixed core dump during Security Discovery

Fixed core dump during Security Discovery

Issue : Core dump occur in (un)owned device discovery on provisionclient sample,
        when build option with SECURED=1 WITH_TCP=1 WITH_CLOUD=1.
Cause : Incorrect condition to set remoteId in OCHandleResponse.
        So, wrong type casting happen as OCDiscoveryPayload,
        and then core dump occure in OCCMDiscoveryResource function.
