perf evlist: Fix parsing with no sample_id_all bit set

The perf_evlist__event2evsel() is changed to handle non-sample events
(such as mmap events) that have no id sample appended i.e. when
sample_id_all is not set.

Note that such events have a fixed format, so that the selected event
(evsel) they are associated with is immaterial.
