virtio-sound: add realize() error cleanup path
QEMU crashes on exit when a virtio-sound device has failed to
realise. Its vmstate field was not cleaned up properly with
qemu_del_vm_change_state_handler().
This patch changes the realize() order as
1. Validate the given configuration values (no resources allocated
by us either on success or failure)
2. Try AUD_register_card() and return on failure (no resources allocated
by us on failure)
3. Initialize vmstate, virtio device, heap allocations and stream
parameters at once.
If error occurs, goto error_cleanup label which calls
virtio_snd_unrealize(). This cleans up all resources made in steps
1-3.
