Fix for the crash in RI sample app

Fix for the crash in RI sample app

The roomserver app crashes due to Invalid free in ocserverrequest.c
Flow: sendResponse->OCDoResponse->HandleAggregateResponse->DeleteServerResponse->OCPayloadDestroy
The payload is already freed in the caller function of sendResponse in InProcServerWrapper.cpp
OCPayloadDestroy is called twice during sendResponse causing a crash in the app.
Hence removing the OCPayloadDestroy called in the method DeleteServerResponse
