Subject: [PATCH 1/5] perf hists browser: Fix callchain print bug on TUI

Currently perf report -g graph option doesn't work as expected and
always work as same as -g fractal.  This was a bug during recent
callchain print code cleanup.

Before:
  $ perf report -g graph

    Children      Self  Command  Shared Object      Symbol
  ================================================================
  -   56.19%    35.41%  sleep    [kernel.kallsyms]  [k] page_fault
     - page_fault
        + 63.02% _dl_relocate_object
        + 36.98% clear_user

After:
    Children      Self  Command  Shared Object      Symbol
  ================================================================
  -   56.19%    35.41%  sleep    [kernel.kallsyms]  [k] page_fault
     - page_fault
        + 35.41% _dl_relocate_object
        + 20.78% clear_user
