Fixed bugs in `disklabel -R...':
- nonstandard sector sizes didn't work because the sector size in the ASCII label was not read before a (default, wrong) sector size was used. - the exit status was 0 after exiting early due to an invalid ASCII label. Abort `disklabel -B...' if the secondary bootstrap doesn't fit.
