[Devel] [PATCH 9/9] ebtables: cleanup table entries during table unregister

[Alexey Dobriyan]

So far table could be unregistered only during module unload.
Which didn't happen, because depending on table entries, module was
pinned enough times to prevent unload at all.

Now table will be unregistered during netns stop, so prevent module
refcount leaks by cleaning up table entries at table unregister time.
