evas/events - removed events_frozen check in evas_event_passes_through()

evas/events - removed events_frozen check in evas_event_passes_through()

in most cases, it is performed twice inside and outside of the function in inefficient way.

and calling of events_frozen in the passes_through() is not understable in the view of functional consistency.

Check is separately would be better.
