ASoC: Intel: fix warning reported by static check tool smatch
The smatch tool report warning: ... CHECK sound/soc/intel/sst-haswell-pcm.c sound/soc/intel/sst-haswell-pcm.c:1110 hsw_pcm_probe() error: buffer overflow\ 'hsw_dais' 4 <= 4 sound/soc/intel/sst-haswell-pcm.c:1112 hsw_pcm_probe() error: buffer overflow\ 'hsw_dais' 4 <= 4 ... fix it by use its own struct member for post-process module, rather than sharing unused pcm member.
