Andrey Smetanin 1f5d2e3bab vhost_net: revert upend_idx only on retriable error ... Fix possible virtqueue used buffers leak and corresponding stuck in case of temporary -EIO from sendmsg() which is produced by tun driver while backend device is not up. In case of no-retriable error and zcopy do not revert upend_idx to pass packet data (that is update used_idx in corresponding vhost_zerocopy_signal_used()) as if packet data has been transferred successfully. v2: set vq->heads[ubuf->desc].len equal to VHOST_DMA_DONE_LEN in case of fake successful transmit.
