Subject: [PATCH] vhost_net: keep acked_feature only for
 NET_CLIENT_DRIVER_VHOST_USER

Keep acked_features in NetVhostUserState up-to-date by function vhost_net_save_acked_features
in function virtio_net_set_features. But nc->peer->info->type maybe NET_CLIENT_DRIVER_TAP or
NET_CLIENT_DRIVER_VHOST_VDPA besides NET_CLIENT_DRIVER_VHOST_USER.

Don't keep acked_features in other type now except NET_CLIENT_DRIVER_VHOST_USER

Fix d29a94eff(vhost-user: Fix the virtio features negotiation flaw)
