tlv: Fix from_dict() symmetry

the to_dict() method generates a {class_name: value} dictionary, for both the nested and non-nested case. However, before this patch, the from_dict() method expects a plain list of child IE dicts in the nested case. This is illogical.

Let's make sure from_dict always expectes a {class_name: value} dict for both nested and non-nested situations.
