Violin driver does not honor clone volume size

[Sean McGinnis]

It's possible to create a volume from a source volume with a different size. The create_cloned_volume call into the driver could have a larger volume['size'] than the source volume. So the driver will need to create the clone, then check if it needs to extend the volume to a new size.
