[patch 10/12] s390: remove ioctl32 from dasdcmb.

[Martin Schwidefsky]

[patch 10/12] s390: remove ioctl32 from dasdcmb.

From: Cornelia Huck <cohuck@xxxxxxxxxx>

The ioctl32_conversion routines will be deprecated: Remove them from
dasd_cmb and handle the three cmb ioctls like all other dasd ioctls.

Signed-off-by: Martin Schwidefsky <schwidefsky@xxxxxxxxxx>
