Fix missing variables in slf4j Logger

I happened to find the following methods have called slf4j Logger without variables whereas {} exists.

org.apache.hadoop.hbase.master.procedure.ReopenTableRegionsProcedure#executeFromState
org.apache.hadoop.hbase.replication.regionserver.SerialReplicationChecker#canPush(org.apache.hadoop.hbase.wal.WAL.Entry, org.apache.hadoop.hbase.Cell)

With my quick patch, I was able to log the condition appropriately at least for SerialReplicationChecker.

2019-02-14 02:34:46,365 TRACE [Time-limited test] regionserver.SerialReplicationChecker(258): The sequence id for Mock for Entry, hashCode: 2138280514 is continuous, pass
