[PATCH 1/2] erofs-utils: dump: read packed inode only by valid packed_nid

[Yue Hu]

From: Yue Hu <huyue2 at coolpad.com>

Since dedupe feature is also using the same feature bit as fragments.
Meanwhile, add missing dedupe feature to feature_lists[].

Fixes: a6336feefe37 ("erofs-utils: dump: support fragments")
