qemu: fix IRQ routing setup
Do the setup for all PCI slots, not only the third.
Also remove the bogus message, as slot 3 may carry
any device, not only NICs.
This makes IRQ setup simliar to SeaBIOS.
SeaBIOS assignments (with patch for logging added,
and a bunch of pci devices for testing purposes):
PCI IRQ [piix]: bdf=00:01.3 pin=1 line=10
PCI IRQ [piix]: bdf=00:03.0 pin=1 line=11
PCI IRQ [piix]: bdf=00:04.0 pin=1 line=11
PCI IRQ [piix]: bdf=00:05.0 pin=1 line=10
PCI IRQ [piix]: bdf=00:06.0 pin=1 line=10
PCI IRQ [piix]: bdf=00:1d.0 pin=1 line=10
PCI IRQ [piix]: bdf=00:1d.1 pin=2 line=10
PCI IRQ [piix]: bdf=00:1d.2 pin=3 line=11
PCI IRQ [piix]: bdf=00:1d.7 pin=4 line=11
