Fixed memory handling of HandleSingleResponse

Fixed memory handling of HandleSingleResponse

As identified in the RI code review, the options and token
were leaked and had some interesting behavior if the options count
was zero.  This patch corrects those, and repairs some return
values that were inconsistent and detected while chaising the
memory around.
