preflight: Prevent possible UaF if usb device is removed while preflight is in progress
The device serial number is only used by reference, however since the preflight helper runs in a separate thread the usb device might be invalidated before the preflight operation is complete, leading to a use-after-free when passing on the device info, followed by accessing the device serial number. By copying the serial number this can be avoided.
