android: CameraDevice: Return const shared_ptr& by camera()
CameraDevice::camera() originally returns shared_ptr. It is
mandatory to make a copy by calling camera() in this way. There
is no need of copying if a caller needs the reference of the
camera like const shared_ptr<Camera> &cam = camera(). That is, it
is a caller that copying is required. This changes the return
type of camera() to const shared_ptr&, so that we are able to
reduce one redundant copy in the above case.
