[f2fs-dev] [PATCH] mkfs.f2fs: fix parent dentry for lost+found

The ".." entry of lost+found currently points to lost+found itself,
while the inode's i_pino field correctly points to the root inode.

As a result, a filesystem freshly created by mkfs.f2fs is immediately
reported as corrupted by fsck.f2fs, which validates the ".." entry
against i_pino.

Set the ".." entry to the root inode instead.
