edje: fix the map state issue.

While the part state switching, map won't gonna be disabled again,
due to the incorrect state checking.

If there param1 indicates the current state with map off.
then it should disable the map obviously.
But It assumed the param1 is the previous state, not the current!,
so the map didn't go disabled state.

It was intended to avoid the duplicated map state setting.
So to keeping the intention, now it disable the map, only if
the map is actually enabled.

So both are fine.
