[ Upstream commit d873997192ddcacb5333575502be2f91ea4b47b8 ]

Fix GCC warning with W=1, previous cleanup did not remove unnecessary
variable.

sound/soc/sof/intel/hda-dai.c: In function ‘hda_link_pcm_prepare’:

sound/soc/sof/intel/hda-dai.c:265:31: warning: variable ‘hda_stream’
set but not used [-Wunused-but-set-variable]
265 | struct sof_intel_hda_stream *hda_stream;
| ^~~~~~~~~~
