evas/evas_map - added workaround code to remove afterimage problem.

Sine the last frame is not updated when map is disabled,
Afterimage problem is happened in software rendering.
Need to find out the reason in the rendering engine then fix it.
However, it's hard to fix the problem now, added a just workaround code temporary.

This problem will be fixed later or be removed when the rendering engine is refactored completely.
