Always return last partition end address in 512B blocks
For 4K disks 'endofpart' is an index of the last 4K sector used by partition. mdadm is using number of 512-byte sectors, so value returned by get_last_partition_end must be multiplied by 8 for devices with 4K sectors. Also, unused 'ret' variable has been removed. Signed-off-by: Mariusz Dabrowski <mariusz.dabrowski@intel.com> Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com>
