Hans de Goede 415548d884 usb: ehci: poll_int_queue check real qtd, not the overlay 
When we first start an int queue, the qh's overlay area is all zeros. This
gets filled by the hc with the actual qtd values as soon as it advances
the queue, but we may call poll_int_queue before then, in which case we
would think the transfer has completed as the hc has not yet copied the
qt_token to the overlay, so the active flag is not set.

This fixes this by checking the actual qtd token, rather then the overlay.
This also fixes a (theoretical) race where we see the completion in the
overlay and free and re-use the qtd before the hc has completed writing back
the overlay to the actual qtd.
