This patch introduces a new feature, F2FS_FEATURE_LOST_FOUND, which is set by mkfs. mkfs creates a directory named lost+found, which saves unreachable files. If fsck finds a file which has no parent, or its parent is removed by fsck, the file will be placed under lost+found directory by fsck. lost+found directory could not be encrypted. As a result, the root directory cannot be encrypted too. So if LOST_FOUND feature is enabled, let's avoid to encrypt root directory.
