  1. fix possible concurrent map read/write 

    there is a potential concurrent map read/write in handleAddOrUpdatePod()
in pkg/network/node/networkpolicy.go

handleAddOrUpdatePod() has to get the networkPolicyPlugin lock before
calling isOnPodNetwork() because that can call getPodIP() which reads
the localPodIPs map. If the lock is not grabbed there could be a
concurrent read/write of the map

this patch grabs the lock before calling isOnPodNetwork()
