powerpc/perf: Fix pmu_count to count only nest imc pmus

Browse source

[ Upstream commit de34787f10 ]

"pmu_count" in opal_imc_counters_probe() is intended to hold
the number of successful nest imc pmu registerations. But
current code also counts other imc units like core_imc and
thread_imc. Patch add a check to count only nest imc pmus.
