decoder: retain proxy surface until the GstVaapiPicture is destroyed.

Browse source 
Keep a valid reference to the proxy in GstVaapiPicture so that frames
marked as "used for reference" could be kept during the lifetime of the
picture. i.e. don't release them too soon as they could be re-used right
away.
