Handling of this case was not correct. TRB size must be multiple of maxpacket for all control out transfer. dma sync function should also be called before start transfer. A routine to delegate transfer for control data has been extracted out from dwc3_ep0_do_control_data. Same routine has been called from ep_queue too in case of pending flag is set.

But , If I see original dwc3_ep0_do_control_data, then it does hard code to ep0.
