virtio-mem-pci: force virtio version 1
Trying to run simple virtio-mem-pci examples currently fails with
qemu-system-x86_64: -device virtio-mem-pci,id=vm0,memdev=mem0,node=0,
requested-size=300M: device is modern-only, use disable-legacy=on
due to the added safety checks in 9b3a35ec8236 ("virtio: verify that legacy
support is not accidentally on").
As noted by Conny, we have to force virtio version 1. While at it, use
qdev_realize() to set the parent bus and realize - like most other
virtio-*-pci implementations.
Fixes: 0b9a2443a48b ("virtio-pci: Proxy for virtio-mem")
