ALSA: usb-audio: Disable autosuspend for Lenovo ThinkStation P620
If USB autosuspend is enabled, both front and rear panel can no longer detect jack insertion. Enable USB remote wakeup, i.e. needs_remote_wakeup = 1, doesn't help either. So disable USB autosuspend to prevent missing jack detection event.
