Exclude backup set size from info for block incremental backups.
As calculated this size is not correct since it does not include the parts of prior block incrementals that are required to make the current block incremental valid. At best this could be approximated and the resulting values might be very confusing. For now, at least, exclude this metric for block incremental backups.
