    libusb: consider bad fd as a broken event
    
    Application can use libusb_get_pollfds to get pollfds from libusb then
    close the fd themselves. This cause the hotplug thread unable to leave
    because it will be consider as a invalid event then loop forever instead
    of a broken event that should be quit immediately.
