Public bug reported:

Kernel patch
https://github.com/torvalds/linux/commit/b2acd1dc3949cd60c571844d495594f05f0351f4
introduced a dependency of openvswitch on ip_gre. ip_gre kernel module
creates gre0 and gretap0 interfaces that are present in all network
namespaces (they are note separated).

This makes neutron-netns-cleanup not deleting namespace as it still
thinks there are devices in namespace (gre0, gretap0).

** Affects: neutron
