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.
