ALSA: ac97: fix a double free in snd_ac97_controller_register()
[ Upstream commit 830988b6cf197e6dcffdfe2008c5738e6c6c3c0f ]
If ac97_add_adapter() fails, put_device() is the correct way to drop
the device reference. kfree() is not required.
Add kfree() if idr_alloc() fails and in ac97_adapter_release() to do
the cleanup.
Found by code review.
