3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Elder <el...@inktank.com>
(cherry picked from commit df6ad1f97342ebc4270128222e896541405eecdb)
Move init_bio_iter() and iter_bio_next() up in their source file so
the'll be defined before they're needed.
