Arnaldo Carvalho de Melo 3b2f17ad17 perf parse-events: Check if the software events array slots are populated 
To avoid a NULL pointer dereference when the kernel supports the new
feature but the tooling still hasn't an entry for it.

This happened with the recently added PERF_COUNT_SW_CGROUP_SWITCHES
software event.
