naviframe: Check if item is valid in _tizen_effect_enabled_get()

Naviframe transition begins in deferred animator callback after item is
pushed or popped.

If an item is destructed and item destructor function is called before
deferred animator callback is called, then the item is NULL in deferred
animator callback and it caused crash due to the lack of NULL check.
