AbsListView invalidates data when it isn’t changed

When setItemChecked is called for AbsListView, it does not check if the
value has changed or not. Then it invalidates the data by setting
mDataChanged to true and also requests a layout. This CL changes the
behavior and does not invalidate data or make a layout request when
the old and the new values are same.
