In the commit 38a2d2eda8 ("pcm: dmix: Do not discard slave reported
delay in status result"), the PCM dmix hwptr update code was rewritten
to follow the slave PCM hwptr update. This is based on the similar
change in PCM dshare, the commit faf53c197c.
There was a bug in the commit 38a2d2eda8 regarding the PCM state
change, and it was addressed in commit 3752e6b873 ("pcm: dmix: Fix
the inconsistent PCM state"). However, we've hit yet another bug in
this commit. Namely, the hwptr update was forgotten in the
snd_pcm_dmix_sync_ptr0() function. So the hwptr value passed from
snd_pcm_dmix_status() isn't properly stored, and it screws up at some
long run occasionally.
This patch covers the bug by replacing with the right value.
