ceph: fix compat_ioctl for ceph_dir_operations
The ceph_ioctl function is used both for files and directories, but only
the files support doing that in 32-bit compat mode.
On the s390 architecture, there is also a problem with invalid 31-bit
pointers that need to be passed through compat_ptr().
Use the new compat_ptr_ioctl() to address both issues.
Note: When backporting this patch to stable kernels, "compat_ioctl:
add compat_ptr_ioctl()" is needed as well.
