In recent patches new mambers to _qemuAgentDiskAddress struct were introduced to keep optional CCW address sent by the guest agent. These two members are a struct to store CCW address into and a boolean to keep track whether the CCW address is valid. Well, we can hold the same information with a pointer - instead of storing the CCW address structure let's keep just a pointer to it.
