[NETNS][IPV6] ip6_fib - clean node use namespace
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.
