I think you should remove the add oneway=yes.
There are a lot of highway=motorway_link that are no oneways and are not 
tagged with oneway=no. Most mappers do not use oneway=no, because the 
common understanding of oneway is that oneway=no is superfluous.
I know that most of these links should be referenced by two ways, but at 
the moment they aren't.

I have started a quick look around. In each country I needed 1 try only 
to get a motorway_link without a oneway tag, where it should be oneway=no.
France: http://www.openstreetmap.org/browse/way/30069642
Germany: http://www.openstreetmap.org/browse/way/4927295
Luxemburg: http://www.openstreetmap.org/browse/way/23002279
Swiss: http://www.openstreetmap.org/browse/way/57727007
Italy: seems to be ok (I didn't find a quick example)
