Description

Running e2fsck on a DNE filesystem where LFSCK was run reported:

Entry '..' in <195395086>/<195395122> (195395122) has an incorrect filetype (was 18, should be 1).
Entry '..' in <602879868>/<602879869> (602879869) has an incorrect filetype (was 18, should be 1).
Entry '..' in <134818057>/<134818059> (134818059) has an incorrect filetype (was 18, should be 1).
Entry '..' in <134818057>/<134818064> (134818064) has an incorrect filetype (was 18, should be 1).
Entry '..' in <134818057>/<134818066> (134818066) has an incorrect filetype (was 18, should be 1).

This is because the entry file_type has a flag EXT2_DIRENT_LUFID when the dirdata feature stores the FID in the directory entry, and it should be masked when checking the file type.
