### Environment

* Dubbo version: 3.0.3

### Steps to reproduce this issue

1. 启动 provider `-Ddubbo.application.register-mode=instance`
2. 启动 consumer `dubbo.application.service-discovery.migration=FORCE_APPLICATION`
3. 使用 `dubbo admin` 创建 mesh 路由
4. `org.apache.dubbo.registry.client.InstanceAddressURL#getParameters` 不能获取真正的 url 参数，导致路由规则匹配失败

5. 原因在于 `getProtocolServiceKey()` 方法是从`RpcContext`中获取，此时获取的`protocolServiceKey` 为 null，导致获取的为 instance 参数，实际需要获取对应服务的参数。
```
    public Map<String, String> getParameters() {
        String protocolServiceKey = getProtocolServiceKey();
        if (StringUtils.isEmpty(protocolServiceKey)) {
            return getInstance().getAllParams();
        }
        return getServiceParameters(protocolServiceKey);
    }
```
```
    public String getProtocolServiceKey() {
        return RpcContext.getServiceContext().getProtocolServiceKey();
    }
```

String[] parameterTypeList = invocation.getCompatibleParamSignatures();
        Object[] parameters = invocation.getArguments();
        for (DubboRouteDetail dubboRouteDetail : dubboRouteDetailList) {
            List<DubboMatchRequest> matchRequestList = dubboRouteDetail.getMatch();
            if (CollectionUtils.isEmpty(matchRequestList)) {
                return dubboRouteDetail;
            }
            boolean match = true;
            
            for (DubboMatchRequest dubboMatchRequest : matchRequestList) {
                if (!DubboMatchRequest.isMatch(dubboMatchRequest, methodName, parameterTypeList, parameters,
                        sourcesLabels,
                        new HashMap<>(), invocation.getAttachments(),
                        new HashMap<>())) {
                    match = false;
                    break;
                }
            }
            if (match) {
                return dubboRouteDetail;
            }
        }
        return null;
    }
    protected synchronized void computeSubset() {
        if (CollectionUtils.isEmpty(invokerList)) {
            this.subsetMap = null;
            return;
        }
        if (vsDestinationGroup == null) {
