[PATCH 5/6] ac97: make remove callback of ac97 driver void returned

[Dawei Li <set_pte_at@xxxxxxxxxxx>]

Since commit fc7a6209d571 ("bus: Make remove callback return
void") forces bus_type::remove be void-returned, it doesn't
make much sense for any bus based driver implementing remove
callbalk to return non-void to its caller.

This change is for ac97 bus based drivers.
