Linux 5.12 compat: bio->bi_disk member moved
The struct bio member bi_disk was moved underneath a new member named bi_bdev. So all attempts to reference bio->bi_disk need to now become bio->bi_bdev->bd_disk. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Coleman Kane <[email protected]> Closes #11639
