[PATCH 37/42] perf tools: Removing hists pair argument from output path

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

The hists pointer is now part of the 'struct hist_entry'.

And since the overhead and baseline columns are split now, there's no
reason to pass it through the output path.
