From: Eric Blake <ebl...@redhat.com>
QAPI code generators currently create a 'void *data' member as
part of the anonymous union embedded in the C struct corresponding
to a QAPI union. However, directly assigning to this member of
the union feels a bit fishy, when we can assign to another member
of the struct instead.
