This patch fix audio record functionality for some Full speed sound blaster devices.
Issue: Sometimes transaction complete indication is coming from HW one frame later.
Solution: If scan_periodic process now frame or previous frame now-1 and sitd transaction
is not finished yet, exit scan_periodic function and check the same transaction in the next frame.
