The NFS CLONE_RANGE defintion was wrong and thus never worked. Fix this
by simply using the btrfs ioctl defintion.

It follows btrfs BTRFS_IOC_CLONE_RANGE lead on ioctl number and
arguments.

It can be called by user space to CLONE two files.
Follow btrfs lead and define NFS_IOC_CLONE same as BTRFS_IOC_CLONE.
Thus we don't mess up userspace with too many ioctls.
