Remove unneded ac97 indirection accessing its state
Searching for "inspiration" to convert another device to qdev, I got ac97. Once I understood a bit of qdev, found that ac97 used a not needed indirection. To protect the unaware, just fixed it. Later, Juan. Signed-off-by: Juan Quintela <quintela@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
