From: Huang Ying <ying.huang@intel.com>
This is just a cleanup patch, no functionality change. In cluster_list_add_tail(), spin_lock_nested() is used to lock the cluster, while unlock_cluster() is used to unlock the cluster. To improve the code readability. Use spin_unlock() directly to unlock the cluster.
