Subject: [PATCH] ASoC: Intel: Skylake: remove unused 'out_fmt' variable

Commit 4cd9899f0d16 introduced struct skl_module_fmt* out_fmt without
using it. Compiling with W=1 gives the below warning, fix it.

sound/soc/intel/skylake/skl-topology.c: In function ‘skl_tplg_update_buffer_size’:
sound/soc/intel/skylake/skl-topology.c:301:34: warning: variable ‘out_fmt’ set but not used [-Wunused-but-set-variable]

This is a harmless warning and is only being fixed to reduce the noise
with W=1 in the kernel.

Fixes: 4cd9899f0d16 ("ASoC: Intel: Skylake: Add multiple pin formats")
