02b61f38d3 ("hw/virtio: incorporate backend features in features")
4daa5054c5 ("enable vrings in vhost_dev_start() for vhost-user devices")
vhost-user-blk frontend now will send VHOST_USER_SET_VRING_ENABLE(0) before
VHOST_USER_GET_VRING_BASE.
blk backend doesn't support VIRTIO_F_RING_RESET, so ignore this queue
disable if no device feature VIRTIO_F_RING_RESET.
