Christoph Hellwig 87283ce621 iomap: fix submission side handling of completion side errors
[ Upstream commit 4ad357e39b ]

The "if (dio->error)" in iomap_dio_bio_iter exists to stop submitting
more bios when a completion already return an error.  Commit cfe057f7db
("iomap_dio_actor(): fix iov_iter bugs") made it revert the iov by
"copied", which is very wrong given that we've already consumed that
range and submitted a bio for it.
