Philippe Mathieu-Daudé efd6b3d176 Revert "hw/net/virtio-net: make VirtIONet.vlans an array instead of a pointer" 
Per https://lore.kernel.org/qemu-devel/7798584d-e861-47b7-af52-2c2efb67a4de@proxmox.com/:

Loading a VM state taken with v10.1.2 or older doesn't work anymore,
using the script [*] we get:

  kvm: VQ 1 size 0x100 < last_avail_idx 0x9 - used_idx 0x3e30
  kvm: load of migration failed: Operation not permitted: error while loading state for instance 0x0 of device '0000:00:13.0/virtio-net': Failed to load element of type virtio for virtio: -1
  qemu-system-x86_64: Missing section footer for 0000:00:13.0/virtio-net
  qemu-system-x86_64: Section footer error, section_id: 41

[*]:
