USB - Formalize polling mode and fix ohci interrupt storm

* Formalize entering and leaving polling mode via usb_set_polling().

* Call bus->methods->do_poll() once when leaving polling mode to
  catch-up any lost interrupts.

* OHCI now acknowledges interrupts from the interrupt handler when
  it finds itself in polling mode to prevent the interrupt from
  storming.  The interrupts are recorded for later use.
