[ Upstream commitb44686c839] Fragments aren't limited by Z_EROFS_PCLUSTER_MAX_DSIZE. However, if a fragment's logical length is larger than Z_EROFS_PCLUSTER_MAX_DSIZE but the fragment is not the whole inode, it currently returns -EOPNOTSUPP because m_flags has the wrong EROFS_MAP_ENCODED flag set. It is not intended by design but should be rare, as it can only be reproduced by mkfs with `-Eall-fragments` in a specific case. Let's normalize fragment m_flags using the new EROFS_MAP_FRAGMENT.
