When a load option points to a physical UsbIo controller, whose device path contains UsbClass or UsbWwid node, old logic unconditionally treats it as a short-form device path and expands it. But the expanding gets the exactly same device path, and the device path is passed to BmGetNextLoadOptionDevicePath() which then passes this device path to BmExpandUsbDevicePath() again. This causes a infinite recursion. The patch avoids the USB short-form expanding when the device path points to a physical UsbIo controller.
