From: Huang Ying <ying.huang@intel.com>
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.
