xfs: xfs_iozero can return positive errno

commit cddc116228cb9d51d3224d23ba3e61fbbc3ec3d2 upstream.

It was missed when we converted everything in XFs to use negative error
numbers, so fix it now. Bug introduced in 3.17 by commit 2451337 ("xfs: global
error sign conversion"), and should go back to stable kernels.

Thanks to Brian Foster for noticing it.
