Konstantin Belousov 46ed9da5fc Do not spuriously re-enable disabled io_apic pin on EOI for some configurations. 
If EOI suppression is supported but reported ioapic version is so old
that it does not has EOI register (weird virtualization setup), fix
Intel trick of eoi-ing by flipping pin type (edge/level) to account
for the disabled pin.
