Geoffrey McRae a8677bcc8f libavcodec/dcadec: adjust the `ch_layout` when downmix is active 
Applications making use of this codec with the `downmix` option are
segfaulting unless the `ch_layout` is overridden after `avcodec_open2`
as can be seen in projects like MythTV[1]

This patch fixes this by overriding the ch_layout as done in other
decoders such as AC3.
