vaapisink: fix GstVideoOverlay::expose() implementation.

Now that we always track the currently active video buffer, it is
not necessary to automatically increase its reference since this is
implicitly performed in ::show_frame() through the get_input_buffer()
helper from GstVaapiPluginBase class.

This is a regression from a26df80.
