ENGR00231773-8 ASRC: prevent user app from processing input/output processing
To finish a buffer convert in ASRC, user should 1. prepare input buffer,
2. prepare output buffer 3. wait for output buffer's completion 4.wait
for input buffer's comletion. The flow make user application ugly.
In this patch, pack steps above to 1 stop: ASRC_CONVERT.
