文件下载地址若失效，会走onDownloadSuccess回调

http错误码为403，但是会走`onDownloadSuccess()`回调，可以修复下

代码如下：
```
HttpRequest.DOWNLOAD(
ActivityUtils.getTopActivity(), downloadUrl,
file,
new OnDownloadListener() {
@Override
public void onDownloadSuccess(File file) {
progressDialog.dismiss();
if (file.length() > 0) {
//下载完毕后安装apk文件
AppUtils.installApp(file);
} else {
ToastUtils.showShort("apk文件大小为0KB，更新失败！");
}
}

@Override
public void onDownloading(int progress) {
KLog.d("下载进度：" + progress);
//更新进度
progressDialog.setProgress(progress);
}

@Override
public void onDownloadFailed(Exception e) {
ToastUtils.showShort("下载失败，原因：" + e.getMessage());
}
}
);
```

Start by tracing the HttpRequest.DOWNLOAD entry point and the OnDownloadListener callback handling. Reproduce the issue with the provided URL, which returns HTTP 403, and verify that failed responses invoke onDownloadFailed rather than onDownloadSuccess; done when the callback behavior matches the response status.
