      Fix a done list handling bug which exhibits under high shared
      interrupt rate and bus traffic.  As the interrupt register is
      read after checking hcca_done_head, there was a small chance
      of dropping a done list.  Ignore OHCI_WDH interrupt bit if
      hcca_done_head is zero so that OHCI_WDH is processed later.
