Fix variant choice

Init() must be passed the variant number, not a variant ID, so setting the
variant to Chess (which has number 0 in the variants table) got confused
with V_SAME for staying in the same variant, and thus did not work.
The invalid variant number -1 is now used to stay in the current variant.
