musb-new, dfu: first send request answer then call completions
comment in ep0_txstate() states: "report completions as soon as the fifo's loaded; there's no win in waiting till this last packet gets acked". This is wrong for using dfu. In the dfu usecase we must send a PollTimeout to the host, so the host can wait until the U-Boot Code is ready for answering new usb requests. So the answer which contains the PollTimeout must send *before* U-Boot calls req->complete. The req->complete is used in the dfu case for flushing the medium, when entering DFU_STATE_dfuMANIFEST_SYNC state.
