perf sched: Fix thread reference leak in idle hist processing
timehist_sched_change_event() sets itr->last_thread to NULL at the end
of idle hist processing without calling thread__put() first. The
thread reference was acquired via thread__get() in timehist_get_thread()
(line 2581), so every idle context switch leaks a thread reference when
--idle-hist is active.
Use thread__zput() to properly release the reference before clearing
the pointer.
Fixes: 5d8f17fb5822 ("perf sched timehist: Add -I/--idle-hist option")
