Stefano Garzarella c98267b4fa vhost/vsock: fix incorrect used length reported to the guest ... commit 49d8c5ffad upstream. The "used length" reported by calling vhost_add_used() must be the number of bytes written by the device (using "in" buffers). In vhost_vsock_handle_tx_kick() the device only reads the guest buffers (they are all "out" buffers), without writing anything, so we must pass 0 as "used length" to comply virtio spec.
