Description
## Issue Description
bug report
### Describe what happened (or what feature you want)
使用spring-cloud-alibbaa集成的sentinel-spring-cloud-gateway-example测试代码
①通过网关访问后端服务,路由里配置一个错误的端口导致连接不上时,请求返回500,,exceptionQps统计数据有计数
②通过网关访问后端服务,接口能连接上,但是后端服务代码异常,请求同样返回500,,exceptionQps统计数据一直显示为0
### Describe what you expected to happen
请求同样是500 希望都能统计
### How to reproduce it (as minimally and precisely as possible)
1. 使用spring-cloud-alibbaa集成的sentinel-spring-cloud-gateway-example测试代码
2. 将网关路由配置错的端口,请求访问返回500,exceptionQps会计数
3. 将网关路由配置对的端口,但代码内部使用 10/0 这种错误代码,请求返回500,exceptionQps不会计数
### Tell us your environment
spring-cloud-alibaba-gateway,2.2.1.RELEASE

Contributor guide
Research direction
Start with the spring-cloud-alibaba-gateway,2.2.1.RELEASE integration and run the sentinel-spring-cloud-gateway-example described in the report. Compare an unreachable upstream with a reachable upstream that throws an exception, then verify that exceptionQps records both HTTP 500 cases.
