The previous change with this intention didn't quite do it. An embedded item must not be freed itself, but might potentially contain non-embedded elements, which must be freed. So instead of calling ASN1_item_ex_free(), where we can't pass the embed flag, we call asn1_item_embed_free() directly. This changes asn1_item_embed_free() from being a static function to being a private non-static function.
