ASoC: img: remove unused ‘format’

In img_prl_out_hw_params(), 'format' is initialized but never used.
So remove it.

sound/soc/img/img-parallel-out.c: In function ‘img_prl_out_hw_params’:
sound/soc/img/img-parallel-out.c:126:19: warning: variable ‘format’ set but not used [-Wunused-but-set-variable]
  snd_pcm_format_t format;
