Stefan Hajnoczi d4c19cdeeb virtio-serial: add missing virtio_detach_element() call ... Ports enter a "throttled" state when writing to the chardev would block. The current output VirtQueueElement is kept around until the chardev becomes writable again. There are several places in the virtio-serial lifecycle where the VirtQueueElement should be thrown away. For example, if the virtio device is reset then virtqueue elements are no longer valid. This patch adds the discard_throttle_data() function to unmap the scatter-gather list and decrement vq->inuse. This ensures that the VirtQueueElement is freed properly.
