from netbsd-bugs, pr 26545:
It's possible that the ohci interrupt can reach the CPU before the write
over PCI. This results in the done head pointer being NULL. If the
subsequent read of the interrupt status indicates that an OHCI_WDH has
occured then the done pointer should be reread and the pointer nulled.
