These two commits should also be added to make virtio-mem hotplug work with CCW 
and PCI on s390.

s390x/s390-virtio-ccw: Support plugging PCI-based virtio memory devices

Let's just wire it up, unlocking virtio-mem-pci support on s390x.

While at it, drop the "return;" in s390_machine_device_unplug_request(),
to make it look like the other handlers.

virtio-mem-pci: Allow setting nvectors, so we can use MSI-X

Let's do it similar as virtio-balloon-pci. With this change, we can
use virtio-mem-pci on s390x, although plugging will still fail until
properly wired up in the machine.

No need to worry about transitional/non_transitional devices, because they
don't exist for virtio-mem.
