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.
Fixes: a8c06e407ef9 ("usb: separate out sysdev pointer from usb_bus")
