[BugFix] Fix the disk size stats of rowset

[trueeyu]

Why I'm doing:

    // calculated by index + data
    optional int64 total_disk_size = 12;
    // calculated sum(segmentgroup.data_size)
    optional int64 data_disk_size = 13;
    // calculated sum(segmentgroup.index_size)
    optional int64 index_disk_size = 14;

total_disk_size = data_disk_size + index_disk_size

What I'm doing:

When some indexes are created on the table, there will be errors in rowset disk space statistics, which can lead to generate some large files.
