Andreas Rheinhardt a06a2d8943 avcodec/avcodec: Check for more invalid channel layouts ...

In particular, check the provided channel layout for encoders
without AVCodec.ch_layouts set. This fixes an infinite loop
in the WavPack encoder (and maybe other issues in other encoders
as well) in case the channel count is zero.
