The VIRTIO_NET_F_CTRL_VLAN feature requires the support of
vhost-user backend. But it will be advertised to guest driver
as long as it's enabled by users in QEMU, while it's not
supported by vhost-user backend. This patch fixes this issue.

Fixes: 72018d1e1917 ("vhost-user: ignore qemu-only features")

It's not clear in the spec that, whether vlan filtering is
also best-effort:
