Subject: [PATCH 2/8] perf sched: Free thread->priv using priv_destructor

In many perf sched subcommand saves priv data structure in the thread
but it forgot to free them.  As it's an opaque type with 'void *', it
needs to register that knows how to free the data.  In this case, just
regular 'free()' is fine.
