fib6_del_route has redundant code

Hi all, I think the following code in fib6_del_route in the latest kernel is useless. 1125 if (fn->leaf == NULL && fn->fn_flags&RTN_TL_ROOT) 1126 fn->leaf = &ip6_null_entry; ip6_null_entry will never be unlinked from fn->leaf now, that is, fn->leaf == NULL will never meet.
