The c partition doesn't need to be shrunk by a sector since it's not
used as a gmirror provider, and only the slices that end at the end of
the disk/provider their slicing.  So a disk with two consecutive
slices, say a and d, only d needs to be reduced by 1 sector since a
doesn't end at the end of the disk anyways.
