接口级别注册时，泛化调用需要请求两次才能正常返回结果 #2591
Description
Environment
- Server: Dubbo-go, branch release-3.1
- Client: Dubbo-go, branch release-3.1
- Protocol: Dubbo
- Registry: zk
Issue description
使用release-3.1分支的dubbogo进行接口级别的泛化调用时，需要请求2次，才能返回正常结果。
参考dubbo-go-sample/generic/default中的例子：
如下，服务端dubbogo 指定registry-type: interface
registries:
zk:
protocol: zookeeper
timeout: 3s
address: 127.0.0.1:2181
registry-type: interface
当client进行如下调用时，第一次会提示Failed to invoke the method $invoke，第二次惨能正常返回结果
func callGetUser(refConf config.ReferenceConfig) {
service := refConf.GetRPCService().(*generic.GenericService)
resp, _ := service.Invoke(
context.TODO(),
"GetUser1",
[]string{"java.lang.String"},
[]hessian.Object{"A003"},
)
fmt.Println(resp)
<-time.After(time.Second)
resp, _ = service.Invoke(
context.TODO(),
"GetUser1",
[]string{"java.lang.String"},
[]hessian.Object{"A003"},
)
fmt.Println(resp)
}
结果如下，第一次调用报错，返回结果nil，第二次正常
