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

Browse source 
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.
