Currently indexes for netdevices come sequentially one by
one, and the same stays true even for devices that are
created for namespaces.
Side effects of this are:
* lo device has not 1 index in a namespace. This may break
some userspace that relies on it (and AFAIR something
really broke in OpenVZ VEs without this);
* after some time namespaces will have devices with indexes
like 1000000 os similar. This might be confusing for a
human (tools will not mind).
So move the (currently "global" and static) ifindex variable
on the struct net, making the indexes allocation look more
like on a standalone machine.
Moreover - when we have indexes intersect between namespaces,
we may catch more BUGs in the future related to "wrong device
was found for a given index".

Applied and tested against netns49. Works fine.
