fix compat handling of FICLONERANGE, FIDEDUPERANGE and FS_IOC_FIEMAP

Unlike FICLONE, all of those take a pointer argument; they do need
compat_ptr() applied to arg.

Fixes: d79bdd52d8be ("vfs: wire up compat ioctl for CLONE/CLONE_RANGE")
Fixes: 54dbc1517237 ("vfs: hoist the btrfs deduplication ioctl to the vfs")
Fixes: ceac204e1da9 ("fs: make fiemap work from compat_ioctl")
