usbcore: resume device resume recursion
This patch (as717b) removes the existing recursion in hub resume code: Resuming a hub will no longer automatically resume the devices attached to the hub. At the same time, it adds one level of recursion: Suspending a USB device will automatically suspend all the device's interfaces. Failure at an intermediate stage will cause all the already-suspended interfaces to be resumed. Attempts to suspend or resume an interface by itself will do nothing, although they won't return an error. Thus the regular system-suspend and system-resume procedures should continue to work as before; only runtime PM will be affected. The patch also removes the code that tests state of the interfaces before suspending a device. It's no longer needed, since everything gets suspended together.
