f2fs: improve print log in f2fs_sanity_check_ckpt()
As Park Ju Hyung suggested: "I'd like to suggest to write down an actual version of f2fs-tools here as we've seen older versions of fsck doing even more damage and the users might not have the latest f2fs-tools installed." This patch give a more detailed info of how we fix such corruption to user to avoid damageable repair with low version fsck.
