qemu: address: Handle all the video devices within a single loop

Since 133fb140 moved the validation of a video device into a separate
function, the code handling PCI slot assignment for video devices has
been the same for both the primary device and the secondary devices.
Let's merge these and thus handle all the devices within the existing
'for' loop.
