block: copy ioprio in __bio_clone_fast() and bounce
We need to copy the io priority, too; otherwise the clone will run with a different priority than the original one. Fixes: 43b62ce3ff0a ("block: move bio io prio to a new field") Signed-off-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Jean Delvare <jdelvare@suse.de> Fixed up subject, and ordered stores.
