        src/sys/dev/pci: cmdide.c

Log Message:
ignore interrupt when not expecting one, particularly don't invoke
the irqack in this case

seems cmdide doesn't honour WDCTL_IDS when executing polled commands,
and there is a race where the irqack call interferes with polled
command and causes a lockup
