[Devel] [PATCH rh7] venet: Don't kill venet0 on the node

[Cyrill Gorcunov]

In case if there were new net-namespace created on the node,
upon its exit we clean up the venet0 host device occasionally.
Fix it testing if net is really ours one.

For some reason such test is already present on pcs6 so
I presume we missed to merge it in first place.
