qcow2: Fix "total clusters" number in bdrv_check
This should be based on the virtual disk size, not on the size of the image. Interesting observation: With some VM state stored in the image file, percentages higher than 100% are possible, even though snapshots themselves are ignored. This is a qcow2 bug to be fixed another day: The VM state should be discarded in the active L2 tables after completing the snapshot creation.
