Bug description:
[Justification]
`mkfs.ext4 -d` can produce broken filesystems when there are acls in the tree
used as input.
[Test case]
1. dd if=/dev/zero count=0 bs=1M seek=100 of=./fake.img
2. mkdir -p stuff/journal
3. setfacl -m g:adm:rwx stuff/journal
4. mkfs.ext4 -L lala -O -metadata_csum -T default -O uninit_bg fake.img -d
./stuff/
5. sudo mount ./fake.img /mnt
6. Verify that `getfacl /mnt/journal/` returns an error.
7. sudo umount /mnt
8. install libext2fs2 from -proposed.
9. mkfs.ext4 -L lala -O -metadata_csum -T default -O uninit_bg fake.img -d
./stuff/
10. sudo mount ./fake.img /mnt
11. Verify that `getfacl /mnt/journal/` returns acl information, not an error.
12. sudo umount /mnt
