MLK-23677-1 usb: cdns3: gadget: the initialize value for trb->length should be zero
With commit d2e892c29de0 ("MLK-23595-1 usb: cdns3:
gadget: calculate TDL per TD"), the first trb->length assignment
is moved before the do-while loop, but only considering DEV_VER_V2
situation, in fact, we need to initialize trb->length for all situations.
