md: Clamp to a multiple of the sector size when resizing

We do this when creating md(4) devices, in kern_mdattach_locked(), but
not when resizing the provider.  Apply the same policy when resizing, as
many GEOM classes do not expect to deal with providers for which
pp->mediasize % pp->sectorsize != 0.
