usb: device: fix wrong direction in usb_transfer_ep_callback 

In case no transfer is ongoing, the usb_transfer_ep_callback consumes
the received data. This is however associated with the wrong test. USB
is host centric, so data reception on the device is signaled by
USB_DC_EP_DATA_OUT and not USB_DC_EP_DATA_IN.
