Subject: [PATCH] perf/arm-cmn: Fix HN-F class_occup_id events

A subtle copy-paste error managed to slip through the reorganisation
of these patches in development, and not only give some HN-F events
the wrong type, but use that wrong type before the subsequent patch
defined it. Too late to fix history, but we can at least fix the bug.

Fixes: b1b7dc38e482 ("perf/arm-cmn: Refactor HN-F event selector macros")
