drivers/base/node.c: fix compaction sysfs file leak

Browse source 
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: ed4a6d7f06 ("mm: compaction: add /sys trigger for per-node memory compaction")
