Don't clobber d_secperunit in `disklabel -e'. `disklabel -e' replaces all
the values that it doesn't print by defaults. This seems wrong. I want
to be able to see the total number of sectors more than edit it. The
default d_secperunit of (sectors/track * tracks/cylinder * cylinders) is
bogus if sectors/track is only an approximation and more bogus if
sectors/track and tracks/cylinder are dummy values such as 4096 and 1
to defeat ufs's pessimizations.
