Subject: [PATCH] fib_trie: Fib walk rcu should take a tnode and key instead of
 a trie and a leaf

This change makes it so that leaf_walk_rcu takes a tnode and a key instead
of the trie and a leaf.

The main idea behind this is to avoid using the leaf parent pointer as that
can have additional overhead in the future as I am trying to reduce the
size of a leaf down to 16 bytes on 64b systems and 12b on 32b systems.
