perf sched: Use thread__put() in free_idle_threads()

Browse source

free_idle_threads() calls thread__delete() directly instead of
thread__put(), bypassing the reference counting lifecycle.  Under
REFCNT_CHECKING builds, this leaks the pointer handle since
thread__delete() frees the object without going through the refcount
wrapper.

The idle threads are created via thread__new() (refcount=1) in
get_idle_thread().  Callers get additional references via thread__get()
which they release with thread__put().  free_idle_threads() drops the
base reference — thread__put() is the correct call, matching the
thread__new() acquisition.
