This removes commented out/dead code from floppy.c

The code in question has been commented out for quite a while (at least as 
far as I can see) and I see no reason for it to clutter up the source any 
longer.
If, in the future, someone sees a real need to resurrect this code then 
they can still find it in the revision history.
Let's kill the cruft :)
