syzbot reported the following circular locking dependency:

  xs->mutex -> netdev lock -> pnodes_lock -> net->xdp.lock -> xs->mutex

The pnodes_lock -> net->xdp.lock edge is recorded when
ipvlan_device_event(NETDEV_UNREGISTER) calls unregister_netdevice_many()
while holding pnodes_lock.  A nested NETDEV_UNREGISTER notification for
an IPvlan device enters xsk_notifier(), which acquires net->xdp.lock.
