ALSA: pcm: Add __force to cast in snd_pcm_lib_read/write()
The snd_pcm_lib_read() and snd_pcm_lib_write() inline functions have
the explicit cast from a user pointer to a kernel pointer, but they
lacks of __force prefix.
This fixes sparse warnings like:
./include/sound/pcm.h:1093:47: warning: cast removes address space of expression
Fixes: 68541213720d ("ALSA: pcm: Direct in-kernel read/write support")
