perf stat: Fix per-socket output bug for uncore events
This patch fixes a problem reported by Andi Kleen on perf
stat when measuring uncore events:
# perf stat --per-socket -e uncore_pcu/event=0x0/ -I1000 -a sleep 2
It would not report counts for the second socket. That was due to a
cpu mapping bug in print_aggr().
This patch also fixes the socket numbering bug for <not counted>
events.
