ASoC: Intel: fix unused-variable warning in probe_codec

In configurations with CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC=n,
gcc warns about an unused variable:

sound/soc/intel/skylake/skl.c: In function ‘probe_codec’:
sound/soc/intel/skylake/skl.c:729:18: error: unused variable ‘skl’ [-Werror=unused-variable]
  struct skl_dev *skl = bus_to_skl(bus);
                  ^~~
cc1: all warnings being treated as errors
