perfmon: fix pmc hw indices out-dated when multiple pmc
When adding two or more events using a single "set pmc",
the pmc hardware indices might be out-dated due to kernel
reschdeduling the perf_event hardware counters.
E.g. set pmc cpu-cycles cache-misses
Solution:
Open and enable all the events first, then aquire the
indices from the kernel.
