USB: serial: metro-usb: fix unthrottle race
If the completion handler races with unthrottle() both functions may try
to resubmit the same interrupt-in urb, but at most one will succeed.
Fix the unthrottle logic using a throttle-requested flag so that only
one attempt to resubmit the urb is made to avoid logging an error.
