Subject: [PATCH 1/2] perf header: Fix numa topology printing

From: Namhyung Kim <namhyung@...nel.org>

Andrew reported that the commit 7e94cfcc9d20 ("perf header: Use pre-
processed session env when printing") regresses the header output.  It
was because of a missed string pointer calculation in the loop.
