Subject: Updating L3 LCO watermarks for HW406803

In DD1 there is a bug in how the LCO home region is calculated so
that the wrong bit44 vaule might be used. In the long run this
works out to about half of the LCO home region being dropped.
To help mitigate this, we're halfing watermarks for LCO's.
