  KVM: x86/pmu: fix masking logic for MSR_CORE_PERF_GLOBAL_CTRL (2024-01-04 16:31:27 +0100)

This is technically not a KVM patch, but I am sending it anyway considering that:

- the patch is doing nothing but undoing a Boolean logic brain fart, restoring
  the pre-6.0 logic

- the function is literally called intel_guest_get_msrs and I am touching only
  the "guest" field, so the non-KVM effects are clearly nil

- this part of the file is often marked as "KVM" in the commit summaries, and
  sent via the KVM tree with Acked-by (usually from PeterZ, whom I am CCing)

- we are pretty close to the release but many people are still in Christmas
  vacation mode/mood

- the bug is not theoretical, Paul described the reproducer as triggering
  "rarely but intolerably often"

- writing this explanation almost took more time than writing the patch,
  thus proving that I reaallyy would like this in 6.7

Thanks,

Paolo
