Subject: [PATCH v2 3/8] vhost: Replace vq->private_data access by backend accesors
Date:   Thu, 16 Apr 2020 09:56:38 +0200

This function still places backend directly in private_data, instead of
use the accesors created on ("cbfc8f21b49a vhost: Create accessors for
virtqueues private_data"). Using accesor.

Fixes: ("7ce8cc28ce48 tools/virtio: Add --reset=3Drandom")
