btrfs_scan_one_device() needs SB, instead of doing it from scratch could
use btrfs_get_bdev_and_sb()
Please see

your patch actually reverts the changes. btrfs_get_bdev_and_sb does not
work and it was a pretty nasty bug, we've spent a long afternoon
catching it.
Ah! It explains why we had a different btrfs_read_dev_super().
Thanks.
