firewire: Only free ORBs that completed the initial transaction. In some situations we can receive the ORB status write before we have received the ORB pointer write response. When this happens, we assume that the fw_transaction is finished and free the ORB struct containing the fw_transaction. This fix make the status write logic only accept status writes for ORBs where the initial ORB pointer write transaction finished.
