Fix IO-APIC edge IRQ handling. IRQ_INPROGRESS was cleared spuriously
if a new edge happened while we were still processing the previous
one.
Then, if a _third_ edge came in, it would actually cause a reentrant
irq handler invocation, because the original INPROGRESS bit was now
lost.
This was actually seen on IDE in PIO mode.
