  - fs/ntfs3: Fix memory leak if ntfs_read_mft failed Label ATTR_ROOT in ntfs_read_mft() sets is_root = true
    and ni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC and alloc ni->dir.alloc_run.
    However two states are not always consistent and can make memory leak. 1) attr_name in ATTR_ROOT does not
    fit the condition it will set is_root = true but NI_FLAG_DIR is not set. 2) next attr_name in ATTR_ALLOC
    fits the condition and alloc ni->dir.alloc_run 3) in cleanup function ni_clear(), when NI_FLAG_DIR is set,
    it frees ni->dir.alloc_run, otherwise it frees ni->file.run 4) because NI_FLAG_DIR is not set in this
    case, ni->dir.alloc_run is leaked as kmemleak reported: unreferenced object 0xffff888003bc5480 (size 64):
