ASoC: msm: qdsp6v2: Handles additional flac metadata

Currently, metadata such as min/max block size is sent only for first

and, subsequently, framedrops in decoding of second stream and onwards
by sending these additional flac metadata, dsp receives stream-wise
metadata and decodes without dropping
