[PATCH 1/3] perf tools: Put proper period for for samples without PERIOD sample_type

[Jiri Olsa]

We use PERF_SAMPLE_PERIOD sample type only for frequency
setup -F (default) option. The -c does not need store period,
because it's always the same.

In -c case the report code uses '1' as  period. Fixing
it to perf_event_attr::sample_period.
