Modified Files:
        src/sys/arch/x86/x86: intr.c

Log Message:
Restore the behaviour intended by rev 1.51 with the patch I actually
send out for testing. The wrong version ended up in the commit.
Original description:
Don't use the legacy interrupt when deciding how to route IOAPIC pins.
On some modern systems not all devices have the PCI interrupt line
set, typically the cardbus bridge is affected and it would result in
different interrupt vectors used for the same IOAPIC pin.
To allow this, simplify the code by checking for an existing match first
and only allocate a new entry if that doesn't exist. For the IOAPIC case
don't bother with the reserveration on the primary CPU for ISA
interrupts, just use them.
