Don't clobber d_secperunit in disklabel -e'. disklabel -e' replaces all

Browse Source 
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.
