efl_ui_focus_layer: avoid a call to NULL

Summary:
efl_ui_focus_layer_enable_set(obj, EINA_FALSE) can be called before
registered_manager assigned

Test Plan:
1. EINA_LOG_LEVELS=eo:2 elementary_test -to menu
2. terminate the elemetary_test
3. check that there is no focus_manager warning about a call to NULL
