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.
