kingst-la2016: Upload firmware to correct USB configuration 1 

The ezusb_upload_firmware() routine opens the USB device and selects the
current configuration. The specified value must match the previously read
configuration descriptor. This commit unbreaks the firmware download for
MinGW builds which link against libusb-1.0.20-rc3-event-abstraction-v4.
