Subject: mm, swap: improve readability via make spin_lock/unlock balanced
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.
