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.
