usb: host: ehci: use correct device pointer for dma ops
commit 02a10f061a3f8bca1b37332672f50a107198adbe upstream. commit a8c06e407ef9 ("usb: separate out sysdev pointer from usb_bus") converted to use hcd->self.sysdev for DMA operations instead of hcd->self.controller, but forgot to do it for hcd test mode. Replace the correct one in this commit.
