USB: core: fix device node leak

commit e271b2c9 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).

Fixes: 69bec725 ("USB: core: let USB device know device node")
