[PATCH OLK-6.6] erofs: handle NONHEAD !delta[1] lclusters gracefully

From: Gao Xiang <hsiangkao(a)linux.alibaba.com> stable inclusion from stable-v6.6.64 commit f466641debcbea8bdf78d1b63a6270aadf9301bf category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBA6RL CVE: CVE-2024-53234 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 0bc8061ffc733a0a246b8689b2d32a3e9204f43c ] syzbot reported a WARNING in iomap_iter_done: iomap_fiemap+0x73b/0x9b0 fs/iomap/fiemap.c:80 ioctl_fiemap fs/ioctl.c:220 [inline] Generally, NONHEAD lclusters won't have delta[1]==0, except for crafted images and filesystems created by pre-1.0 mkfs versions. Previously, it would immediately bail out if delta[1]==0, which led to inadequate decompressed lengths (thus FIEMAP is impacted). Treat it as delta[1]=1 to work around these legacy mkfs versions. `lclusterbits > 14` is illegal for compact indexes, error out too.
