Subject: [PATCH v7 24/24] perf test stat_all_metrics: Ensure missing events
 fail test

Issue reported by Thomas Falcon and diagnosed by Kan Liang here:
https://lore.kernel.org/lkml/d44036481022c27d83ce0faf8c7f77042baedb34.camel@intel.com/
Metrics with missing events can be erroneously skipped if they contain
FP, AMX or PMM events.
