[PATCH v1 1/1] usb: gadget: Use correct endianness of the wLength field for WebUSB

[Andy Shevchenko]

WebUSB code uses wLength directly without proper endianness conversion.
Update it to use already prepared temporary variable w_length instead.

Fixes: 93c473948c58 ("usb: gadget: add WebUSB landing page support")
