Subject: [PATCH 349/359] Always return last partition end address in 512B
 blocks
References: bsc#1081910

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.
