ecore_evas: Check for null ptr deref

This patch fixes a tentative crash owing to ptr deference.
Unlike ecore_evas_object_cursor_set and ecore_evas_object_cursor_device_set,
ecore_evas_cursor_set uses Ecore_Evas *ee before calling internal function which
internally checks null ptr dereference of Ecore_Evas *ee.
