Simply retain the coordinates in the starting structure when running pdb2gmx.
Note that pdb2gmx will generate some spurious bond and angle interactions in the
case of rigid water, so either (1) remove those interactions in the topology
afterwards or (2) separate the protein and water, process the protein, and
simply paste back the water coordinates and proceed.
