I went and tried this patch but with usb_autopm_get_interface_no_resume instead
and the original bug I was trying to fix with a Yubikey hid security key came
back, so something is still wrong here.

I went ahead and filed a bug to track this here:
https://bugs.chromium.org/p/chromium/issues/detail?id=764112

I'll find some time to dig into this deeper and understand why this device
ends up getting stuck in active instead of suspending when all handles are
closed.

Thanks,
Benson
