vhdx: Fix zero-fill iov length
Fix the length of the zero-fill for the back, which was accidentally using the same value as for the front. This is caught by qemu-iotests 033. For consistency, change the code for the front as well to use the length stored in the iov (it is the same value, copied four lines above).
