efl_ui_image: Fix unnecessary unload of memfile_set.

Summary:
In D11392, fixed to call file_unload when doing memfile_set.
Therefore, "load,error" callback was called while unloading object
that was not loaded when first load with memfile_set.
So fix it to avoid unnecessary unloading.

Test Plan:
{F3871804}
cp ./test_imge.c ./efl/
cd efl
gcc -o test_image test_image.c -g `pkg-config --cflags --libs elementary`

./test_image
Loading image...
Async file load failed.
Image is ready to show.
