Set bus and disk type correctly when creating VMs from ISO images

The onImageChange() function in
edit/kubevirt.io.virtualmachine/VirtualMachineVolume/type/vmImage.vue
includes logic to set type="cd-rom" and bus="sata" when you select an
ISO image as the source for a volume.  This commit applies the same
logic when initially creating a VM from a given image.
