fib_trie: remove potential out of bound access
[ Upstream commit aab515d7c32a34300312416c50314e755ea6f765 ]
AddressSanitizer [1] dynamic checker pointed a potential
out of bound access in leaf_walk_rcu()
We could allocate one more slot in tnode_new() to leave the prefetch()
in-place but it looks not worth the pain.
Bug added in commit 82cfbb008572b ("[IPV4] fib_trie: iterator recode")
