vmdk: Support version=3 in VMDK descriptor files
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".
