Atari floppy: Rename disk_type to atari_disk_type

Commit edfaa7c3

    Driver core: convert block from raw kobjects to core devices

    This moves the block devices to /sys/class/block. It will create a
    flat list of all block devices, with the disks and partitions in one
    directory. For compatibility /sys/block is created and contains symlinks
    to the disks.

introduced a global disk_type variable in <linux/genhd.h>, causing the
following compile error on Atari:

    drivers/block/ataflop.c:93: error: conflicting types for 'disk_type'
    include/linux/genhd.h:21: error: previous declaration of 'disk_type' was here

Rename the local disk_type variable in drivers/block/ataflop.c to
atari_disk_type, to avoid the conflict.
