Commit 509d39aa22909c0ed1aabf896865f19c81fb38a1 added support for read
only VMDKs of version 3.
This commit fixes the probe function to correctly handle descriptors of
version 3.
This commit has two effects:
1. We no longer need to supply '-f vmdk' when pointing to descriptor
files of version 3 in qemu/qemu-img command line arguments.
2. This fixes the scenario where a VMDK points to a parent version 3
descriptor file which is being probed as "raw" instead of "vmdk".
