Whoever wrote the original floppy labeling code apparently didn't grok
the difference between DIOCSDINFO and DIOCWDINFO.  I just fixed this.

When I tested this recently, I was only writing new boot blocks, which
seems to work with the old code.

Anyway, here's my change, which should show up on lamp eventually:
