avfilter/buffersrc: fix overriding unknown channel layouts with negotiated one Fixes ffplay playback of unknown layouts, when SDL directly supports the audio format, such as: ffplay -f lavfi anullsrc=cl=2C,aformat=s16 Without the patch, "Channel layout change is not supported" errors are generated because buffersrc (unknown 2 channel) and buffersink (stereo) negotiated a stereo layout, but the stereo layout was never stored in the BufferSourceContext. This fixes a regression of 7251f909721a570726775acf61b2b9c28a950c76, but this is more of a regression of the avfilter channel layout conversion (1f96db959c1235bb7079d354e09914a0a2608f62).
