Stefan Haberland bfe512fb5b s390/dasd: Fix gendisk parent after copy pair swap

commit c943bfc6af upstream.

After a copy pair swap the block device's "device" symlink points to
the secondary CCW device, but the gendisk's parent remained the
primary, leaving /sys/block/<dasdx> under the wrong parent.

Move the gendisk to the secondary's device with device_move(), keeping
the sysfs topology consistent after the swap.
