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.
