[PATCH 10/13] perf tools: Fix lsdir to set errno correctly

[Arnaldo Carvalho de Melo]

From: Masami Hiramatsu <mhira...@kernel.org>

Fix lsdir() to set correct positive error number (ENOMEM).  Since
"errno" must have a positive error number instead of negative number,
fix lsdir to set it correctly.
