Kevin Wolf c336500df5 vmdk: Fix COW 
When trying to do COW, VMDK wrote the data back to the backing file. This
problem was revealed by the patch that made backing files read-only. This patch
does not only fix the problem, but also simplifies the VMDK code a bit.

This fixes the backing file qemu-iotests cases for VMDK.
