[PATCH v1 0/1] virtio-snd: fix invalid tx/rx message handling logic

[Manos Pitsidianakis <manos.pitsidianakis@linaro.org>]

This is a logic fix for the error handling in the TX/RX virt queue 
handlers. A potential invalid address dereference was reported and fixed 
by Zheyu Ma in <20240322110827.568412-1-zheyuma97@gmail.com>. This patch 
moves the invalid message storage from the stream structs to the virtio 
device struct to

1. make such bug impossible
2. reply to invalid messages again with VIRTIO_SND_S_BAD_MSG, which was 
not possible before.
