[PATCH 5.9 144/391] f2fs: fix to set SBI_NEED_FSCK flag for inconsistent inode

[Greg Kroah-Hartman]

From: Chao Yu <yuch...@huawei.com>

[ Upstream commit d662fad143c0470ad7f46ea7b02da539f613d7d7 ]

If compressed inode has inconsistent fields on i_compress_algorithm,
i_compr_blocks and i_log_cluster_size, we missed to set SBI_NEED_FSCK
to notice fsck to repair the inode, fix it.
