If a qcow2 image uses a 'data-file' on a local block device we can still honour VIR_DOMAIN_BLOCK_RESIZE_CAPACITY but use the capacity of the data-file instead.

The code is modified to first pick the virStorageSource which we'll probe for size based on the config of the VM and uses to determine the new size.
