James Almer 530ca627a3 avcodec/mlpdec: don't depend on context channel layout when setting substream masks ...

If avctx->ch_layout is unset (as it's allowed and even expeced by the
AV_CODEC_CAP_CHANNEL_CONF flag), the code setting substream masks will fail for
stereo and mono layouts unless a downmix channel was requested.
Fix this by deriving the mask with coded values only.

Fixes issue #20764.
