qcow2: Fix "total clusters" number in bdrv_check

Browse source 
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.
