The fourth substream is being discarded, since its not raw audio data,
but an encoded Atmos stream which needs a specialized decoder.

with VLC_BITS = 5. Results for overall audio decode and the get_vlc2 function
in particular are as follows:

When request_channel_layout is 0,
all substreams should be decoded.

Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.
Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.

The faulty values rippled further down the codepath causing a
hard-to-track segfault in the assembly code.
