Log Message:
In wdcintr(), it !WDCF_IRQ_WAIT, read the status register anyway to clear a
possible pending interrupt. This should avoid the interrupt loop described
in PR kern/15841.
It is safe to read status here, because if we're not waiting for an interrupt
we have no command pending, so the device should be idle.
