QModbusReply seems to never finish in some rare cases: For instance if a request is sent and before the reply arrives, the modbus adapter is unplugged. This change should keep upper logic working which relies on requests finishing eventually. Also fixes the issue that we emit finished() multiple times if QModbusClient retries multiple times and emits error() for each attempt. We're only interested in a single result anyways.
