writeback: fix done_index when hitting the wbc->nr_to_write
When write_cache_pages finishes writing out a folio, it fails to update
done_index to account for the number of pages in the folio just written.
That means when range_cyclic writeback is restarted, it will be restarted
at this folio instead of after it as it should. Fix that by updating
done_index before breaking out of the loop.
