The fib6_clean_node function should have the network namespace
it is working on. The fib6_cleaner_t structure is extended with the
network namespace field to be passed to the fib6_clean_node function.
The different functions calling the fib6_clean_node function are extended
with the netns parameter when needed to propagate the netns pointer.
