As of virtio spec 1.0, driver must not accept flags which the device
did not offer (section 2.2). However, that flag is apparently being
accepted, causing silent exception to be triggered in rte_vhost. This
results in all negotiated features to be rejected in rte_vhost.
This patch is a workaround. Enabling that flag does not enforce us to do
