api: Simplify API version check for flavor description

Browse Source 
Unlike the check for extra specs, the check for whether to include a
description field or not is driven entirely by API version rather than
API version and policy. We can therefore move the checks inside the
functions that generate the response rather than duplicating them
elsewhere.
