android: camera_device: Reset config_ if Camera::configure() fails

Browse source 
The config_ pointer is reset in all error paths of the
CameraDevice::configureStreams() function, except when
Camera::configure() fails. Fix it by using a local unique pointer to
store the configuration until the end of the function, to avoid similar
issues in the future.
