[ALSA] Fix control/status mmap with shared PCM substream
The flag to avoid 32bit-incompatible mmap for control/status records should be outside the pcm substream instance since a substream can be shared among multiple opens. Now it's flagged in pcm_file list that is directly assigned to file->private_data. Also, removed snd_pcm_add_file() and remove_file() functions and substream.files field that are not really used in the code.
