Fix NullPointerException happens in dumpCheckin

Currently dumpCheckin passes a null object to create
the contructor of NetworkStatsCollection.Key but the
constructor requires non-null object. Thus, it caused
the NPE in dumpCheckin. To fix this exception, create
an NetworkIdentitySet() object instead of using an
null object.
