android: camera_device: Fix null pointer dereference

Browse Source 
Commit 7532caa2c7 ("android: camera_device: Reset config_ if
Camera::configure() fails") reworked the configuration sequence to
ensure that the CameraConfiguration pointers gets reset when
configuration fails. This inadvertently causes a null pointer
dereference, as the CameraStream constructor accesses the camera
configuration through CameraDevice::cameraConfiguration() before the
internal config_ pointer is set.

Fix this by passing the configuration pointer explicitly to the
CameraStream constructor.
