Since there is no serialization mechanism (e.g. the RTNL lock) between
llist_add() in net_complete_free() and llist_del_all() in
net_complete_free(), it is possible that net_complete_free() finds 'struct
net' as soon as net_complete_free() added it to the defer_free_list.

Did you see a real issue or is this based on AI report ?

netns_wq is single thread workqueue.

Indeed, this patch is not needed.
