You're going to be fine. Overfill could do two things: Get additional blow-by that ends up in your airbox and/or too deep in the sump and is high enough to be into the crankshaft, causing foaming. Either way, just check to see if you are in the mid-range of the sight glass - exact on the mark isn't important.
I wouldn't sweat your adventure - likely no damage at all done.
