iomap: export iomap_iter_advance() and return remaining length
As a final step for generic iter advance, export the helper and update it to return the remaining length of the current iteration after the advance. This will usually be 0 in the iomap_iter() case, but will be useful for the various operations that iterate on their own and will be updated to advance as they progress.
