perf hist: Correct hist_entry->mem_info refcounts
The 'struct mem_info' is created by iter_prepare_mem_entry() at the
beginning and destroyed by iter_finish_mem_entry() at the end.
So if it's used in a new hist_entry, it should be cloned.
Simplify (hopefully) the logic by adding some helper functions and by
not holding the refcount in the temporary entry.
