Missed initialization the variable of pmu::capabilities when extract the initialization code of hisi_pmu->pmu into a function. HISI UNCORE PMU drivers counters that not support context exclusion. So we have to advertise the PERF_PMU_CAP_NO_EXCLUDE capability. This ensures that perf will prevent us from handling events where any exclusion flags are set.
