Matias Ezequiel Vara Larsen 6a072fa02c sound: remove ControlMessage parameter from release() 
This commit removes ControlMessage from the release() method. The
backends process the release() command immediately thus not requiring the
audio backend to notify guest later. The notification happens in the
device after the cmd is processed. This also removes the need of
handling descriptors in the audio backend. This commit fixes the tests
in pw.

Synopsis

   vhost-device-sound --socket <SOCKET> --backend <BACKEND>

Description

   A virtio-sound device using the vhost-user protocol.

Options

     --socket <SOCKET>
            vhost-user Unix domain socket path

     --backend <BACKEND>
            audio backend to be used [possible values: null, pipewire, alsa]

     -h, --help
            Print help

     -V, --version
            Print version

Examples

Launch the backend on the host machine:

host# vhost-device-sound --socket /tmp/snd.sock --backend null

With QEMU, you can add a virtio device that uses the backend's socket with the following flags:

-chardev socket,id=vsnd,path=/tmp/snd.sock \
-device vhost-user-snd-pci,chardev=vsnd,id=snd
