Don't think about it.

I know this probably isn't the answer you were hoping for, but that's really your only option. The continuity of FOX's X-Men films is so inconsistent that all you can do is call it a plot-hole or a retcon and be done with it. Whether or not that's a good thing is a different discussion, but X-Men Origins: Wolverine has been particularly ignored by later entries in this franchise.
