[PATCH 1/3] perf ui/tui: Reset output width for hierarchy

[Namhyung Kim]

When --hierarchy option is used, each entry has its own hpp_list to show
the result.  But it missed to update width of each column.

Before:

  - 46.29% 48.12%        netctl-auto
     + 31.44% 29.25%        [kernel.vmlinux]
     + 8.52% 11.55%        libc-2.22.so
     + 5.19% 6.91%        bash
  + 10.75% 11.83%        wpa_cli
  + 8.25% 2.23%        swapper
  + 6.45% 5.40%        tr
  + 4.81% 8.09%        awk
  + 4.15% 2.85%        firefox
  + 3.86% 2.53%        sh

After:

  -  46.29%  48.12%        netctl-auto
      +  31.44%  29.25%        [kernel.vmlinux]
      +   8.52%  11.55%        libc-2.22.so
      +   5.19%   6.91%        bash
  +  10.75%  11.83%        wpa_cli
  +   8.25%   2.23%        swapper
  +   6.45%   5.40%        tr
  +   4.81%   8.09%        awk
  +   4.15%   2.85%        firefox
  +   3.86%   2.53%        sh
