Namhyung Kim 84d1b20132 perf stat: Fix crash with --per-node --metric-only in CSV mode
The following command will get segfault due to missing aggr_header_csv
for AGGR_NODE:

  $ sudo perf stat -a --per-node -x, --metric-only true

Committer testing:

Before this patch:

  # perf stat -a --per-node -x, --metric-only true
  Segmentation fault (core dumped)
  #

After:

  # gdb perf
  -bash: gdb: command not found
  # perf stat -a --per-node -x, --metric-only true
