The created structure is not really a proper QAPI object, so we cannot

This seems fragile to me; having to code QAPI usage differently
depending on whether the containing struct was malloc'd or not (and
therefore whether someone will call qapi_free_MigrateSetParameters or
not) looks awkward to maintain. We have
visit_type_MigrateSetParameters_members, could that be used as a cleaner
way to free all members of the struct without freeing the struct itself?
Should the QAPI generator start generating qapi_free_FOO_members to
make such cleanup easier?
