[PATCH 39/42] perf diff: Removing the total_period argument from output code

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

The total_period is available in struct hists data via the 'struct
hist_entry::hists' pointer. There's no need to carry it through the
output code path.

Removing 'struct perf_hpp::total_period' pointer, because it's no longer
needed.
