memdisk: MBR not recognized correctly
This fixes a small inaccuracy in memdisk:
get_disk_image_geometry() does not use MBR data to detect disk
geometry, since it checks MBR signature at wrong offset.
This normally does not cause problems, because memdisk guesses a
reasonable value, if no MBR is found.
