The error handling in bxt_sst_dsp_init() got changed in a way that
it now derefences an uninitialized pointer when printing a warning
about the device not being found:

sound/soc/intel/skylake/bxt-sst.c: In function 'bxt_sst_dsp_init':
sound/soc/intel/skylake/bxt-sst.c:567:14: error: 'skl' may be used uninitialized in this function [-Werror=maybe-uninitialized]

As we do have a valid device pointer available at the call site,
let's use that instead.

Fixes: 9fe9c7119283 ("ASoC: Intel: Skylake: Move sst common initialization to a helper function")
