Subject: [PATCH 244/359] ddf: use 64bit 'size', not 32bit 'info->size' for
 create.
References: bsc#1081910

The 'size' field of mdu_disk_info_t is 32bit and should not be used
except for legacy ioctls.  super-ddf got this wrong :-(

This change makes it possible to create ddf arrays which used more than
2TB of each device.
