Subject: image data get/set pairing issue

I found a bug about pairing
evas_object_image_data_get/set(eng_image_data_get/put).

It was added to count checked_out for paring
eglMapImageSEC/eglUnmapImageSEC.
 
In case of calling evas_object_image_data_set() twice after calling
evas_object_image_data_get(), dyn.checked_out has -1.

Then, if evas_object_image_data_get() and evas_object_image_data_set()
is call, it can't call eglUnmapImageSEC().
 
If dyn.checked_out has minus, it can make some problem.

So, I fixed this problem.
 
Please find enclosed patch file and let me know if I misunderstood.
