[PATCH v2 10/27] compat_ioctl: ubd, aoe: use blkdev_compat_ptr_ioctl

[Arnd Bergmann <arnd@xxxxxxxx>]

These drivers implement the HDIO_GET_IDENTITY and CDROMVOLREAD ioctl
commands, which are compatible between 32-bit and 64-bit user space and
traditionally handled by compat_blkdev_driver_ioctl().

As a prerequisite to removing that function, make both drivers use
blkdev_compat_ptr_ioctl() as their .compat_ioctl callback.
