net: use net->count to check whether a netns is alive or not
The previous idea was to check whether a net namespace is in net_exit_list or not. It doesn't work, because net->exit_list is used in __register_pernet_operations and __unregister_pernet_operations where all namespaces are added to a temporary list to make cleanup in a error case, so list_empty(&net->exit_list) always returns false.
