sched: Fix memory leakage in build_sched_groups() In build_sched_groups() we don't need to call get_group() for cpus which are already covered in previous iterations. Calling get_group() would mark the group used and eventually leak it since we wouldn't connect it and not find it again to free it. This will happen only in cases where sg->cpumask contained more than one cpu (For any topology level). This patch would free sg's memory for all cpus leaving the group leader as the group isn't marked used now.
