Subject: [PATCH] Revert "x86: acpi: workaround Windows not handling name
 references in Package properly"

This reverts commit 44d975ef340e2f21f236f9520c53e1b30d2213a4.

breaks VirtIO network adapters in (at least) the German ISO of Windows
Server 2022. The fix itself was for

> Issue is not fatal but as result acpi-index/"PCI Label ID" property
> is either not shown in device details page or shows incorrect value.

so revert and tolerate that as a stop-gap, rather than have the
devices not working at all.
