ALSA: pcm: Define snd_pcm_mmap_data_{open|close}() locally
snd_pcm_mmap_data_open() and _close() are defined as inline functions
in the public sound/pcm.h, but those are used only locally in
pcm_native.c, hence they should be better placed there.
Also, those are referred as callbacks, the useless inline is dropped.
