When the binlog was rotated due to @@max_binlog_size, the values of the binlog_shapshot_file and binlog_snapshot_position were inconsistent in case of non-transactional DML. The position was refering to the old file, while the filename was of the new file after rotation. This patch makes them consistent by making sure the position is also refering to the new file.
