ASoC: rsnd: ssi: remove unnesessary period_pos
period_pos can always be calculated by byte_pos and byte_per_period, there is no reason to maintain this variable in rsnd_dai_stream. This patch removes period_pos from rsnd_ssi and calculates next_period_byte with consideration of actual byte_pos value.
