hw/audio/virtio-sound: mark the device as unmigratable

Browse Source 
The virtio-sound device is currently not migratable. QEMU crashes
on the source machine at some point during the migration with a
segmentation fault.

Even with this bug fixed, the virtio-sound device doesn't migrate
the state of the audio streams. For example, running streams leave
the device on the destination machine in a broken condition.

Mark the device as unmigratable until these issues have been fixed.
