drivers/base/node.c: fix compaction sysfs file leak
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.
Fixes: ed4a6d7f0676 ("mm: compaction: add /sys trigger for per-node memory compaction")
