I think as long as the purpose of rolling the ball was to get it to another teammate that was clearly behind the baseline for the purpose of making a throw-in that this is just incidental and not a violation. I've seen players pick up the ball to inbound it and then drop it so another player can inbound it. In the process of dropping it, it bounced off the wall. It never even came into my mind to call this a violation. Obviously the action in your play is a little different, but in my mind as long as the wall isn't providing an advantage and the ball grazing the wall is unintentional then I'm not going to think twice about it.
