Location service can't get pvtz's endpoint in cn-beijing

[devkanro]

I found location service can't work fine with region cn-beijing and pvtz service.

There are some log for it

I0325 14:19:34.714201   19032 logs.go:41] Invoke GET https://location.aliyuncs.com?Action=DescribeEndpoints&Format=JSON&Id=cn-beijing&ServiceCode=pvtz&SignatureMethod=HMAC-SHA1&SignatureVersion=1.0&Timestamp=2019-03-25T06%3A19%3A34Z&Type=openAPI&Version=2015-06-12 404 (167.1761ms)

    "HostId": "location.aliyuncs.com",
    "Code": "InvalidRegionId",
    "Message": "The specified region does not exist."
}

When I change region to cn-hangzhou, it can works. I think that aliyun private zone only works with region cn-hangzhou. Should we disable use localtion service to find endpoint for pvtz service?
