android: camera_device: Return unique_ptr from createFrameBuffer
Returning a non-managed pointer can cause leaks. Use a unique_ptr<> instead to avoid possible future issues. The std::move() for the planes argument to the FrameBuffer constructor is dropped as it's misleading. FrameBuffer has no constructor that takes an rvalue reference to planes, so the vector was copied despite the move. This only clarifies the intent, no functional change is introduced.
