vmscan: convert direct reclaim tracepoint to DEFINE_TRACE
Mel Gorman recently added some vmscan tracepoints. Unfortunately they are covered only global reclaim. But we want to trace memcg reclaim too. Thus, this patch convert them to DEFINE_TRACE macro. it help to reuse tracepoint definition for other similar usage (i.e. memcg). This patch have no functionally change.
