    VMware: Skip setting vmdk UUID

    After creating a volume from a source volume or snapshot, the VMDK
    driver sets the vmdk (volume in vCenter) UUID to the volume UUID.
    vCenter 6.0+ does not support this operation if the new volume is
    created as a linked clone of the source. This patch skips the UUID
    update operation for linked clone volumes if vCenter version is
    6.0+.
