Remove conditioned-out dsf diagnostic code.

print_dsf was declared in puzzles.h, but never called, and its
definition was commented out. So it probably wouldn't still have
worked anyway. The other commented-out printfs in that file don't look
very useful either, and they just mean more stuff will need messing
about with as I continue to refactor.
