can: kvaser_usb: Ignore CMD_FLUSH_QUEUE_REPLY messages
To avoid kernel warning "Unhandled message (68)", ignore the CMD_FLUSH_QUEUE_REPLY message for now. As of Leaf v2 firmware version v4.1.844 (2017-02-15), flush tx queue is synchronous. There is a capability bit indicating whether flushing tx queue is synchronous or asynchronous. A proper solution would be to query the device for capabilities. If the synchronous tx flush capability bit is set, we should wait for CMD_FLUSH_QUEUE_REPLY message, while flushing the tx queue.
