Subject: [PATCH] sched/fair: Use __schedstat_set() in set_next_entity()
References: bsc#1189999 (Scheduler functional and performance backports)
Patch-mainline: v5.16-rc1
Git-commit: a2dcb276ff9287fcea103ca1a2436383e8583751
schedstat_enabled() has been already checked, so we can use
__schedstat_set() directly.
