If error happened during new net-namespace creation we might
end up having VE reference taken and never put back.
| copy_net_ns
| setup_net
| ...
| net->owner_ve = get_ve(get_exec_env());
| ...
| error = ops_init(ops, net);
| if (error < 0)
| goto out_undo;
| ...
| return error;
| put_user_ns(user_ns);
| net_drop_ns(net);
| net_free(ns);
| kfree(net->gen);
| kmem_cache_free(net_cachep, net);
So lets call for put_ve to balance.
