qcow2: Write v3-compliant snapshot list on upgrade
qcow2 v3 requires every snapshot table entry to have two extra data
fields: The 64-bit VM state size, and the virtual disk size. Both are
optional for v2 images, so they may not be present.
qcow2_upgrade() therefore should update the snapshot table to ensure all
entries have these extra data fields.
