After commit 0caed25cd171 vhost_vdpa_net_load_vlan() started seeing VIRTIO_NET_F_CTRL_VLAN flag and making 4096 calls to the kernel with VIRTIO_NET_CTRL_VLAN_ADD command. However, it forgot to convert the 16-bit VLAN IDs to LE format. On BE machine, the kernel calls failed when they saw "VLAN IDs" greater than 4095, and QEMU then said: "unable to start vhost net: 5: falling back on userspace virtio", and VDPA became disabled.Convert the VLAN ID to LE before putting it into virtio queue.
