Igor Mammedov 89caa45bf3 pci: acpi: Windows 'PCI Label Id' bug workaround 
Current versions of Windows call _DSM(func=7) regardless
of whether it is supported or not. It leads to NICs having bogus
'PCI Label Id = 0', where none should be set at all.

Also presence of 'PCI Label Id' triggers another Windows bug
on localized versions that leads to hangs. The later bug is fixed
in latest updates for 'Windows Server' but not in consumer
versions of Windows (and there is no plans to fix it
as far as I'm aware).

Given it's easy, implement Microsoft suggested workaround
(return invalid Package) so that affected Windows versions
could boot on QEMU.
This would effectvely remove bogus 'PCI Label Id's on NICs,
but MS teem confirmed that flipping 'PCI Label Id' should not
change 'Network Connection' ennumeration, so it should be safe
for QEMU to change _DSM without any compat code.

Smoke tested with WinXP and WS2022
