drivers/perf: hisi: Set correct IRQ affinity for PMUs with no association
For PMUs with no association, the hisi_pmu->on_cpu is initialized according to the NUMA locality but use a wrong CPU for the interrupt affinity. The CPU selected from cpumask_local_spread() can be different from the CPU by the cpuhp callback. Fix this by setting the IRQ affinity to hisi_pmu->on_cpu.
