Baokun Li 4f6f4e5a33 ext4: align max orphan file size with e2fsprogs limit ...

commit 7c11c56eb3 upstream.

Kernel commit 0a6ce20c15 ("ext4: verify orphan file size is not too big")
limits the maximum supported orphan file size to 8 << 20.

However, in e2fsprogs, the orphan file size is set to 32–512 filesystem
blocks when creating a filesystem.

With 64k block size, formatting an ext4 fs >32G gives an orphan file bigger
than the kernel allows, so mount prints an error and fails:

    EXT4-fs (vdb): orphan file too big: 8650752
    EXT4-fs (vdb): mount failed

To prevent this issue and allow previously created 64KB filesystems to
mount, we updates the maximum allowed orphan file size in the kernel to
512 filesystem blocks.
