virtio_snd.h: clarify that `controls` depends on VIRTIO_SND_F_CTLS
As defined in the specification, the `controls` field in the configuration
space is only valid/present if VIRTIO_SND_F_CTLS is negotiated.
From https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html:
5.14.4 Device Configuration Layout
...
controls
(driver-read-only) indicates a total number of all available control
elements if VIRTIO_SND_F_CTLS has been negotiated.
Let's use the same style used in virtio_blk.h to clarify this and to avoid
confusion as happened in QEMU (see link).
