David Hildenbrand 77ae2302ae monitor: Rate-limit MEMORY_DEVICE_SIZE_CHANGE qapi events per device
We want to rate-limit MEMORY_DEVICE_SIZE_CHANGE events per device,
otherwise we can lose some events for devices. We can now use the
qom-path to reliably map an event to a device and make rate-limiting
device-aware.

This was noticed by starting a VM with two virtio-mem devices that each
have a requested size > 0. The Linux guest will initialize both devices
in parallel, resulting in losing MEMORY_DEVICE_SIZE_CHANGE events for
one of the devices.

Fixes: 722a3c783e ("virtio-pci: Send qapi events when the virtio-mem size changes")
