ASoC: msm: qdsp6v2: Update pcm media format block to use correct stream id

Repeat mode is not working in pcm offload path. When two streams
are used in a single session pcm format block should be sent
specific to each stream. Data sent on stream 2 is ignored by DSP
because pcm format block is always sent on stream 1. Fix is to
update pcm media format block to use correct stream id before
data is sent to DSP.
