[PATCH v3 4/7] erofs: kill __packed for on-disk structures

[Gao Xiang <gaoxiang25@huawei.com>]

As Christoph claimed "Please don't add __packed" [1],
I have to remove all __packed except struct erofs_dirent here.

Note that all on-disk fields except struct erofs_dirent
(12 bytes with a 8-byte nid) in EROFS are naturally aligned.
