From: ZheNing Hu <adlternative@xxxxxxxxx>
When we use ref_array_item which is not dynamically allocated and
want to free the space of its member "value" after the end of use,
free_array_item() does not meet our needs, because it tries to free
ref_array_item itself and its member "symref".
Introduce free_ref_array_item_value() for freeing ref_array_item value.
It will be called internally by free_array_item(), and it will help
`cat-file --batch` free ref_array_item's value memory later.
