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.
