[LU-6840] update memory reply data in DNE update replay

• Type: Bug

Description

DNE update replay might update last_rcvd file, but because it will be operated on OSD/OSP directly, so the memory structure (ted/lrd etc) will not be updated by update replay handler, so it needs update these memory structure by itself after each update replay. (see replay_request_or_update() ).

In current implementation, this is done in target_update_lcd(), but multiple slot patch just changed this process, so target_update_lcd needs to be fixed as well.
