Not regardless -- but it is using 64K as a minimum

Hi,
The cluster_size got from backup_calculate_cluster_size(),
MAX(BACKUP_CLUSTER_SIZE_DEFAULT, bdi.cluster_size), is 64K regardless
of the target image's cluster size.
For example:
If the cluster size of source and target qcow2 images are both 16K, the
64K from backup_calculate_cluster_size
