perf report: Speed up exit path 

When cmd_record exits the whole perf binary will exit right after,
so no need to traverse lots of complex data structures freeing them.

Sticked a comment for leak detectives and for a experiment with obstacks
to be performed so that we can speed up freeing that memory.
