kubeedge: fix NodeIp when ks-installer resync

Created by: zhu733756

After enabled KubeEdge components, once the ks-installer restart, the current cmdline cannot find the correct NodeIP. For example：

kubectl get node -o wide | awk '{if(NR == 2){print $6}}'
--
1.1.1.1

It returns the edgenode internalIP:

NAME            STATUS   ROLES                         AGE     VERSION                   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION       CONTAINER-RUNTIME

Change to the following cmdline to fix it:

 kubectl get node -o wide | grep "master" | awk '{if(NR == 1){print $6}}'
192.168.88.6
