device: virtio: snd: Call release_worker in prepare

Since VIRTIO_SND_R_PCM_PREPARE -> VIRTIO_SND_R_PCM_PREPARE is a valid
transition, we need to release the worker if it's already in
VIRTIO_SND_R_PCM_PREPARE state. Or we could trigger

```
Error in handling tx queue: Error in mpsc: send failed because receiver is gone
```

in handle_pcm_queue while sending `desc_chain` to start_pcm_worker
through the `stream_info.sender()`.

BUG=b:202368198
TEST=Run alsa_conformance_test multiple times

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
