drivers/base/node.c: fix compaction sysfs file leak
[ Upstream commit da63dc84befaa9e6079a0bc363ff0eaa975f9073 ]
Compaction sysfs file is created via compaction_register_node in
register_node. But we forgot to remove it in unregister_node. Thus
compaction sysfs file is leaked. Using compaction_unregister_node to fix
this issue.
