ASoC: nau8824: Fix semaphore unbalance at error paths

[ Upstream commit 5628560e90395d3812800a8e44a01c32ffa429ec ]

The semaphore of nau8824 wasn't properly unlocked at some error
handling code paths, hence this may result in the unbalance (and
potential lock-up).  Fix them to handle the semaphore up properly.
