That paper has some flawed assumptions, I think. For one, they tie resuspension linearly to vehicle weight, but say that it's related to the vehicle's wake. It seems that they're confounded by the typical relationship of weight and size (therefore wake). But electric vehicles while heavier, are typically the same size as ICE vehicles. Thus they might break the assumption that greater weight means greater resuspension.
The paper says that resuspension is the largest part of non-emissions particulates, so we have lowered brake sources (because regen means less pad wear) and lower emissions, and probably not greater resuspension. Maybe tire wear is higher. Put those together and it seems like electric vehicles should come out ahead, particularly if we're talking about diesel vehicles.
