perf vendor events amd: Fix Zen 5 MAB allocation events 



The unit masks for PMCx041 vary across different generations of Zen
processors.

Fix the Zen 5 events based on PMCx041 as they incorrectly use the same
unit masks as that of Zen 4.

Fixes: 45c072f2 ("perf vendor events amd: Add Zen 5 core events")
