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:

Fix this by always setting is_root and NI_FLAG_DIR together.
