Takashi Iwai 1be2143fb7 ALSA: pcm: Make mmap status read-only 
The mmap status record should be read-only.  Modifying it from
user-space may screw up things unexpectedly, so let's clear the write
bits at exposing it.

Note that alsa-lib and other known user-space apps access the mmapped
status only as read-only, hence this change shouldn't break the
existing applications.
