usb: host: ehci: use correct device pointer for dma ops

Browse source 
commit a8c06e407e ("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.
