ALSA: compress_offload: Use runtime pointer in snd_compr_poll()

runtime is not used as seen with W=1 :
sound/core/compress_offload.c: In function ‘snd_compr_poll’:
sound/core/compress_offload.c:409:35: error: variable ‘runtime’ set but not used [-Werror=unused-but-set-variable]
  409 |         struct snd_compr_runtime *runtime;
      |                                   ^~~~~~~

Instead of dropping the runtime, use it in the function in place of
stream->runtime
