usb: gadget: uvc: remove references to DMA_ADDR_INVALID
gadget drivers shouldn't touch req->dma at all, since UDC drivers are the ones required to handle mapping and unmapping of the request buffer. Remove references to DMA_ADDR_INVALID so we don't creat false expectations to gadget driver writers.
