S390_CPUMSF uses a raw event type (PERF_TYPE_RAW - refer s390_cpumsf_evsel_is_auxtrace()) not a PMU type value that could be checked in evsel__is_aux_event(). However it sets needs_auxtrace_mmap (refer auxtrace_record__init()), so check that first. Currently, the features that use evsel__is_aux_event() are used only by Intel PT, but that may change in the future.
