USB: musb: resume suspended root hub on disconnect
If this is not done, khubd will not be informed of the disconnect
and will assume the device is still there.
Easily seen when a hub is connected with no device attached to it;
it will autosuspend. When the hub is disconnected, it still shows
up in /proc/bus/usb/devices
