Manos Pitsidianakis 731655f87f virtio-snd: rewrite invalid tx/rx message handling
The current handling of invalid virtqueue elements inside the TX/RX virt
queue handlers is wrong.

They are added in a per-stream invalid queue to be processed after the
handler is done examining each message, but the invalid message might
not be specifying any stream_id; which means it's invalid to add it to
any stream->invalid queue since stream could be NULL at this point.

This commit moves the invalid queue to the VirtIOSound struct which
guarantees there will always be a valid temporary place to store them
inside the tx/rx handlers. The queue will be emptied before the handler
returns, so the queue must be empty at any other point of the device's
lifetime.
