[GitHub] [dubbo] jimiyi opened issue #5052: 配置的executes参数引发的bug

### Environment

* Dubbo version: 2.7.2
* Operating System version: centos
* Java version: 1.8

### Steps to reproduce this issue
接口配置了全局的executes参数后，对并发请求接口做了限制，跟踪代码发现接口请求计数不会扣减，原因如下：
1. 是使用泛化调用的发起的请求
2. 请求经过GenericFilter后，ExecuteLimitFilter(line: 52)方法里可以拿到争取的methodName
3. 外层ProtocolFilterWrapper(line: 159)在扣减接口计数时，外层的invocation，并没有经过GenericFilter过滤，所以拿到的methodName依然是$invoke, 造成计数扣减失败

请尽快修复这个bug
