Takashi Iwai d371588910 ALSA: pcm: Fix mmap without buffer preallocation 
The recent rewrite of the memory allocation helpers also changed the
page extraction to a common helper, snd_sgbuf_get_page().  But this
assumes implicitly that the buffer was allocated via the standard
helper (usually via preallocation), and didn't consider the case of
the manual buffer handling.

This patch fixes it and also covers the manual buffer management.

Fixes: 37af81c599 ("ALSA: core: Abstract memory alloc helpers")
