hda-codec: fix playback rate control
Since commit 1930616b98 "audio: make mixeng optional" the
function hda_audio_output_cb can no longer assume the function
parameter avail contains the free buffer size. With the playback
mixing-engine turned off this leads to a broken playback rate
control and playback buffer drops in regular intervals.
This patch moves down the rate calculation, so the correct
buffer fill level is used for the calculation.
