Let's keep the same behavior as vhost-user-blk.
Some old guests kick virtqueue before setting VIRTIO_CONFIG_S_DRIVER_OK.

Get_inflight_fd is sent only once. When reconnecting to the backend,
qemu sent set_inflight_fd to the backend.

Based on what MST said, is there anything else I need to do?

If the os is not installed and doesn't have the virtio guest driver,
the vhost dev isn't started, so the dev->vdev is NULL.
Reproduce: mount a Win 2019 iso, go into the install ui, then resize
the virtio-blk device, qemu crash.

Sorry, looks like I use the old qemu code, master has fix this issue.
Just ignore this patch.

If the vhost memory layout doesn't change, don't need to call the vhost
backend.
The set_mem_table is time consuming when sending to vhost-user backend.
On aarch64, the edk2 uefi firmware will write the pflash which will
trigger the vhost_commit hundreds of times.
