Group validation expects all events to be of the same PMU; however
is_uncore_pmu() is too wide, it matches _all_ uncore events, even
across PMUs.
This triggers failure when we group different events from different
uncore PMUs, like:
perf stat -vv -e '{uncore_cbox_0/config=0x0334/,uncore_qpi_0/event=1/}' -a sleep 1
Fix is_uncore_pmu() by only matching events to the box at hand.
Note that generic code; ran after this step; will disallow this
mixture of PMU events.
