[NET]: Cleanup pernet operation without CONFIG_NET_NS
If CONFIG_NET_NS is not set, the only namespace is possible.
This patch removes list of pernet_operations and cleanups code a bit.
This list is not needed if there are no namespaces. We should just call
->init method.
Additionally, the ->exit will be called on module unloading only. This
case is safe - the code is not discarded. For the in/kernel code, ->exit
should never be called.
