Subject: [PATCH] ecore_evas: Check for null ptr deref

Summary:
This patch fixes a tentative crash owing to ptr dereference.
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.

Test Plan: Executes test suite
