Bug description:
[Impact]
Mic on Lenovo P620 can not record any sound after S3.
[Fix]
Query the connector status on system resume.
[Test]
With the patch applied, the mic in question works after S3 resume.
Also tested on some other USB audio and they also work fine.
[Where problems could occur]
If there's a USB audio device that doesn't like its connectors being
queried, then this may regress on those devices.
However I suspect this is the default behavior on other OSes, so it's
unlikely to happen.
