btrfs: get rid of endio_repair_workers
This was originally added in commit 8b110e39 ("Btrfs: implement repair function when direct read fails") to avoid a deadlock. In that commit, the direct I/O read endio executes on the endio_workers workqueue, submits a repair bio, and waits for it to complete. The repair bio endio must execute on a different workqueue, otherwise it could block on the endio_workers workqueue becoming available, which won't happen because the original endio is blocked on the repair bio. As of the previous commit, the original endio doesn't wait for the repair bio, so this separate workqueue is unnecessary. Reviewed-by:Josef Bacik <josef@toxicpanda.com> Signed-off-by:
