dsp: codecs: fix range check for audio buffer copying
The range checking for audio buffer copying in function "audio_in_write" is using the incorrect buffer size. Change it to the actual allocated audio buffer size. Change-Id: Ib7aaa2163c0d99161369eb85d09dc2d23d8c787b Signed-off-by: Xiaoyu Ye <benyxy@codeaurora.org>
