ASoC: renesas: rz-ssi: Fix rz_ssi_priv::hw_params_cache::sample_width

commit 2bae7beda19f3b2dc6ab2062c94df19c27923712 upstream.

The strm->sample_width is not filled during rz_ssi_dai_hw_params(). This
wrong value is used for caching sample_width in struct hw_params_cache.
Fix this issue by replacing 'strm->sample_width'->'params_width(params)'
in rz_ssi_dai_hw_params(). After this drop the variable sample_width
from struct rz_ssi_stream as it is unused.
