LU-8587 utils: Fix incorrect indenting in llapi_hsm_log_ct_progress

LU-8587 utils: Fix incorrect indenting in llapi_hsm_log_ct_progress

gcc6 highlights this case of incorrect indenting:
        if (progress_type == CT_RUNNING)
                rc = llapi_json_add_item(&json_items, "current_bytes",
                                         LLAPI_JSON_BIGNUM, &current);
                if (rc < 0)
                        goto err;

Just add the braces around, though logic-wise it's all fine.
