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
