Marton Balint aa5e6017a5 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 7251f90972, but this
is more of a regression of the avfilter channel layout conversion
(1f96db959c).
