Gwenole Beauchesne 4fa2315557 plugins: fix creation of video buffer from another source buffer.
gst_vaapi_video_buffer_new_from_buffer() needs to reference the source
buffer video meta since it would be unreference'd from the get_buffer()
helper function. For other cases, we still use (steal) the newly created
video meta.
