drivers/perf: arm_pmu: Avoid leaking pmu->irq_affinity on error
pmu->irq_affinity will not be freed if an error occurred within arm_pmu_device_probe after of_pmu_irq_cfg has been called. Note that in the case of_pmu_irq_cfg is returning an error, pmu->irq_affinity will not be set, but it should be NULL as pmu was kzalloc'd. Therefore the result kfree(NULL) is benign.
