perf metric: Fix some memory leaks

I found some memory leaks while reading the metric code.  Some are real
and others only occur in the error path.  When it failed during metric
or event parsing, it should release all resources properly.

Fixes: b18f3e365019d ("perf stat: Support JSON metrics in perf stat")
