Bug description:
[Impact]
Rear audio on Lenovo ThinkStation P620 stops working on newer kernel.
[Fix]
Use helper to the correct way to disable USB autosuspend.
[Test]
With the patch applied, the rear audio on Lenovo ThinkStation P620 works
again.
[Where problems could occur]
In a rather unlikely case, if any USB audio wrongly shared same device
ID with P620' USB audios, this patch will disable autosuspend on it.
However, it won't bring any functional impact.
