xfs: don't unconditionally clear the reflink flag on zero-block files
commit cc6f77710a6de6210f9feda7cd53e2f5ee7a7e69 upstream.
If we have speculative cow preallocations hanging around in the cow
fork, don't let a truncate operation clear the reflink flag because if
we do then there's a chance we'll forget to free those extents when we
destroy the incore inode.
