ozone: Don't take a self reference in surfaceless adapter dtor

It's not valid to take a scoped_refptr to yourself inside your destructor
because this in a illegal 0-1 refcount transition.  This is causing our
demo app to crash.

Fix it by not taking a reference to the current surface if the current
surface is |this|.
