Taeung Song 360e071b18 perf tools: Use zfree() to avoid keeping dangling pointers ...

The cases changed in this patch are for when we free but keep the
pointer to the freed area, which is not always a good idea.

Be more defensive and zero the pointer to avoid possible use after
free bugs to take more time to be detected.
