Nicolas Dichtel 4217291e59 netns: don't clear nsid too early on removal 
With the current code, ids are removed too early.
Suppose you have an ipip interface that stands in the netns foo and its link
part in the netns bar (so the netns bar has an nsid into the netns foo).
Now, you remove the netns bar:
 - the bar nsid into the netns foo is removed
 - the netns exit method of ipip is called, thus our ipip iface is removed:
   => a netlink message is sent in the netns foo to advertise this deletion
   => this netlink message requests an nsid for bar, thus a new nsid is
      allocated for bar and never removed.

We must remove nsids when we are sure that nobody will refer to netns currently
cleaned.

Fixes: 0c7aecd4bd ("netns: add rtnl cmd to add and get peer netns ids")
