Issue description

When we try to update APISIXRoute CRD，the ingress controller report the error like this: It looks like this problem only appears when we try to update/delete ports, it works fine with adding new ports. The steps as followed:

1. We first define two ports, 8080 and 8081 The ingress controller create two upstreams correctly

2. change port 8081 to 8083 The error appears: service.spec.ports: port not defined

Environment

• your apisix-ingress-controller version (output of apisix-ingress-controller version --long): 1.4.1

我也遇到过类似的问题，如果svc的port变化了，同步更新apisixroute的话就会出现这个问题，我这边的解决办法是如果port端口发生变化，我会删掉旧的apisixtroute 然后重新创建新的apisixroute
