libpayload: usb: dwc2: Always return 'size' transferred bytes for OUT

Seems like our transferred bytes calculation for OUT transfers that span
    more than one packet had been wrong, and we just got lucky that we never
    noticed it before. The HCTSIZ.xfersize register field we're reading only
    counts bytes transferred by the last packet we sent.

OUT endpoints cannot have short transfers -- every transfer should
    either finish all bytes we wanted to send or end in a proper error
    condition. Therefore, in the absence of an error we can just conclude
    that all input bytes have been transferred.
