[PATCH] ASoC: Intel: Skylake: remove unused 'runtime' variable

[Kirtika Ruchandani]

skl_platform_open() defines and sets 'struct snd_pcm_runtime* runtime'
but does not use it. Compiling with W=1 gives the following warning,
fix it.

sound/soc/intel/skylake/skl-pcm.c: In function âskl_platform_openâ:
sound/soc/intel/skylake/skl-pcm.c:941:26: warning: variable âruntimeâ set but not used [-Wunused-but-set-variable]

This was introduced with the initial driver commit a40e693c7f5e
("ASoC: Intel: Add Skylake HDA platform driver").
This is a harmless warning and is only being fixed to reduce the noise
with W=1 in the kernel.
