Subject: USB: core: fix device node leak
From: Johan Hovold <johan@xxxxxxxxxx>
commit e271b2c909a22a2c13b2d5f77f2ce0091b74540c upstream.
Make sure to release any OF device-node reference taken when creating
the USB device.
Note that we currently do not hold a reference to the root hub
device-tree node (i.e. the parent controller node).
