Fix raw storage volume creation for allocation < capacity.
CreateXMLFrom changes accidentally caused all raw volume creation to be fully allocated (as though allocation == capacity). Fix this. Also force CreateXMLFrom to maintain the previous behavior: sparseness should still be maintained since we search for holes when copying, and the clone behavior hasn't been tested with anything but the broken behavior.
