c29dd73f74fe6020ee0755d938885919a3719194 virtio-md-pci: Handle unplug of virtio based memory devices
While we fence unplug requests from the outside, the VM can still
trigger unplug of virtio based memory devices, for example, in Linux
doing on a virtio-mem-pci device:
# echo 0 > /sys/bus/pci/slots/3/power
While doing that is not really expected to work without harming the
guest OS (e.g., removing a virtio-mem device while it still provides
memory), let's make sure that we properly handle it on the QEMU side.
We'll add support for unplugging of virtio-mem devices in some
configurations next.
