perf hist: Add missing puts to hist__account_cycles
[ Upstream commit c1149037f65bcf0334886180ebe3d5efcf214912 ]
Caught using reference count checking on perf top with
"--call-graph=lbr". After this no memory leaks were detected.
Fixes: 57849998e2cd ("perf report: Add processing for cycle histograms")
