We should definitely not initialise attached_{width,height} here,
because no buffer has ever been attached.

Not initialising attached_{width,height} should not cause any problems
with these checks. By definition there cannot have been any buffers
allocated or attached between creation and the first draw call, so
there are no old buffers to release.
So with that initialisation removed, this is (assuming dEQP still passes):
