sched/fair: Fix cfs_rq_is_decayed() on !SMP
[ Upstream commit c0490bc9bb62d9376f3dd4ec28e03ca0fef97152 ]
We don't need to maintain per-queue leaf_cfs_rq_list on !SMP, since
it's used for cfs_rq load tracking & balancing on SMP.
But sched debug interface uses it to print per-cfs_rq stats.
This patch fixes the !SMP version of cfs_rq_is_decayed(), so the
per-queue leaf_cfs_rq_list is also maintained correctly on !SMP,
to fix the warning in assert_list_leaf_cfs_rq().
Fixes: 0a00a354644e ("sched/fair: Delete useless condition in tg_unthrottle_up()")
