usb: dwc3: ep0: Reset TRB counter for ep0 IN

In control read transfer completion handler, the driver needs to reset the TRB enqueue counter. Since there is one control endpoint structure for each direction, we must also track the TRB enqueue counter for each direction. Currently the driver only resets the TRB counter for control OUT endpoint only. Check for the data direction and properly reset the TRB counter from correct control endpoint.
