ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl
The update of rate_num/den and msbits were factored out to fixup_unreferenced_params() function to be called explicitly after the hw_refine or hw_params procedure. It's called from snd_pcm_hw_refine_user(), but it's forgotten in the PCM compat ioctl. This ended up with the incomplete rate_num/den and msbits parameters when 32bit compat ioctl is used. This patch adds the missing call in snd_pcm_ioctl_hw_params_compat().
