[IPv6]: use container_of() macro in fib6_clean_node() In ip6_fib.c, fib6_clean_node() casts a fib6_walker_t pointer to a fib6_cleaner_t pointer assuming a struct fib6_walker_t (field 'w') is the first field in struct fib6_walker_t. To prevent any future problems that may occur if one day a field is inadvertently inserted before the 'w' field in struct fib6_cleaner_t, (and to improve readability), this patch uses the container_of() macro.
