The only way to un-nocow a +C file is to physically rewrite it into a new
copy. The +C attribute can be removed on existing files only if they are 0
bytes in size.

Try a different/newer kernel version, as noted in my message all of this
doesn't seem to matter anymore, and nocow files can now be reflinked (or +C is
not working anymore and they aren't actually nocow).
