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.
