usb: gadget: rndis: fix Missing req->context assignment
It is crucial to assign each req->context value to struct rndis. The problem happens for multi function gadget (g_multi) when multiple functions are calling common usb_composite_dev control request. It might happen that *_setup method from one usb function will alter some fields of this common request issued by other USB function.
