Fixes gcc '-Wunused-but-set-variable' warning:

sound/soc/intel/haswell/sst-haswell-ipc.c: In function 'hsw_stream_message':
sound/soc/intel/haswell/sst-haswell-ipc.c:669:29: warning: variable 'stage_type' set but not used [-Wunused-but-set-variable]

It is never used since introduction in
commit ba57f68235cf ("ASoC: Intel: create haswell folder and move haswell platform files in")

Thanks for the patch.

I think you could go further in the cleanup and remove both the variable 
declaration and the static inline mst_get_stage_type that will also be 
useless as a consequence of this assignment removal.
