When the helper function _scratch_mkfs_sized is called with small filesystem size and FSTYP=btrfs, it calls mkfs.btrfs with --mixed option to enable mixed mode. However, mkfs.btrfs with --mixed option fails for zoned block devices since btrfs does not support mixed mode together with zoned mode. To avoid this failure, do not set --mixed option when the scratch device is a zoned block device.

Change from the previous post: * Keep change minimum btrfs device size as 256MiB.
