[Qemu-devel] [PATCH v3] iotests: Fix CID for VMDK afl image

[Fam Zheng]

This reverts commit 76bf133c4 which updated the reference output, and
fixed the reference image, because the code path we want to exercise is
actually the invalid image size.

The descriptor block in the image, which includes the CID to verify, has been
invalid since the reference image was added. Since commit 9877860e7bd we report
this error earlier than the "file too large", so 059.out mismatches.

The binary change is generated along the operations of:

  $ bunzip2 afl9.vmdk.bz2
  $ qemu-img create -f vmdk fix.vmdk 1G
  $ dd if=afl9.vmdk of=fix.vmdk bs=512 count=1 conv=notrunc
  $ mv fix.vmdk afl9.vmdk
  $ bzip2 afl9.vmdk
