rculfhash: Simplify lookup_bucket()

They are the same, but I don't think the compiler can optimize it.

And it also helps for understanding the following code.

[ Edit by Mathieu Desnoyers:
  - Add a comment that describes the equivalence between get_count_order
    and fls for this lookup of index + 1. ]
