[PATCH v2] ALSA: 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.

As such, change the remove function for ac97 based drivers to return
void.
