[Stable-9.0.2 05/22] hw/audio/virtio-snd: Always use little endian audio format

[Michael Tokarev]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

The VIRTIO Sound Device conforms with the Virtio spec v1.2,
thus only use little endianness.

Remove the suspicious target_words_bigendian() noticed during
code review.
