Re: [PATCH v2 01/14] perf cs-etm: Fix nVHE per-thread decoding

pid_fmt is unset in per-thread mode because we don't need PIDs, so we can't use it as a hint to determine which EL the host is running at. That results in falling though to the next part where EL1 is treated as guest, which is wrong for nVHE.

Fix it by only returning a guest machine when run from perf kvm where a guest image would be provided, which matches existing behavior in other parts of Perf.
