audio: codec_adapter: Make sure local_buff has enough room for processing 

We need to make sure that the local buffer has enough room to hold
the output of the processing.

This means that for each type of decoding algorithm we need to know
the maximum possible output size and skip processing if local buffer
size is less than that.
