Felipe Balbi 5516847083 usb: dwc3: ep0: fix DMA starvation by assigning req->trb on ep0 ...

If we don't assign a TRB to ep0 requests, we won't be able to unmap
the request later on resulting in starvation of DMA resources.

Fixes: 4a71fcb8ac ("usb: dwc3: gadget: only unmap requests from DMA if mapped")
