ACPI - fixed initialization of pci briges irqtable
ACPI - fixed initialization of pci briges irqtable

- if no IRQ table is found, we report that ACPI cannot map IRQ
  correctly

- fixes mapping of IRQs in KVM because in this case we just fall
  through and use the IRQ configured by BIOS. PCI still reports
  that it failed to use ACPI. It is a hint if things go wrong.
