Subject: [PATCH][next] perf/x86: remove unused variable 'cpu_type'

Since the removal of function x86_pmu_update_cpu_context() by commit
983bd8543b5a ("perf: Rewrite core context handling"), there is no need to
query the type of the hybrid CPU inside function init_hw_perf_events().

Fixes: 983bd8543b5a ("perf: Rewrite core context handling")
