If we set CP_ERROR_FLAG in roll-forward error, f2fs is no longer to proceed any IOs due to f2fs_cp_error(). But, for example, if some stale data is involved on roll-forward process, we're able to get -ENOENT, getting fs stuck. If we get any error, let fill_super set SBI_NEED_FSCK and try to recover back to stable point.
