When tethered rmnet/dun interface probe is failed, the bridge channel platform device is removed in error path. The gadget driver schedule a work to open the bridge channel in probe. Cancel this work in remove before closing the channel. Cancel any pending work while closing the bridge. Otherwise there is a possibility of rx work running in parallel with probe error path. If this happens, rx work access already freed memory.
