sched: Avoid NULL dereference on sd_busy
commit 42eb088ed246a5a817bb45a8b32fe234cf1c0f8b upstream.
Commit 37dc6b50cee9 ("sched: Remove unnecessary iteration over sched
domains to update nr_busy_cpus") forgot to clear 'sd_busy' under some
conditions leading to a possible NULL deref in set_cpu_sd_state_idle().
