    Correct two bugs in fsck_ffs(8) triggered by corrupted filesystems.

    Always create a directory inode structure when a directory inode is
    found in Pass 1 as it is not known whether it will be saved or removed
    in later passes. If it is to be saved the directory inode structure
    is needed to track its status and fsck_ffs(8) will segment fault if
    it does not exist.
