URL: https://github.com/apache/dubbo-go/issues/2550
### Environment

### Issue description
两边实现不一样导致客户端重试计算出来值不一样
## Java
```java
private int calculateInvokeTimes(String methodName) {
int len = getUrl().getMethodParameter(methodName, RETRIES_KEY,
DEFAULT_RETRIES) + 1;
RpcContext rpcContext = RpcContext.getClientAttachment();
Object retry = rpcContext.getObjectAttachment(RETRIES_KEY);
if (retry instanceof Number) {
len = ((Number) retry).intValue() + 1;
rpcContext.removeAttachment(RETRIES_KEY);
}
if (len <= 0) {
len = 1;
}
return len;
}
```
## Go
```go
func getRetries(invokers []protocol.Invoker, methodName string) int {
if len(invokers) <= 0 {
return constant.DefaultRetriesInt
}
url := invokers[0].GetURL()
// get reties
retriesConfig := url.GetParam(constant.RetriesKey,
constant.DefaultRetries)
// Get the service method loadbalance config if have
if v := url.GetMethodParam(methodName, constant.RetriesKey, ""); len(v)
!= 0 {
retriesConfig = v
}
retries, err := strconv.Atoi(retriesConfig)
if err != nil || retries < 0 {
logger.Error("Your retries config is invalid,pls do a check.
And will use the default retries configuration instead.")
retries = constant.DefaultRetriesInt
}
if retries > len(invokers) {
retries = len(invokers)
}
return retries
}
```
