evas: fix performance regression by reducing the unecessary memcpy we are doing. 

Actually copying max is pretty useless and super slow. We usually have something
like 1024 slot in a context, but a very small amount of them are acutally active.
It would be better to actually do some kind of copy on write technique here, but
as Eina_Cow doesn't handle array and we are close to a release, let's be
conservative.
