CameraHAL: Do not return error if AF fails
Fixes b/5612881
Some third-party apps do not handle errors thrown by the camera HAL when they
try to invoke autoFocus while AF is in progress.
The Barcode Scanner, in particular, will quit in this case without releasing
the Camera handle, wreaking all sorts of power-management havoc.
Even though CTS does not mandate it, previous versions of Android and other
camera HAL implementations simply return success in this case. This patch
makes this HAL conform to this behavior.
