Subject: ovl: Put upperdentry if ovl_check_origin() fails
From: Vivek Goyal <vgoyal@xxxxxxxxxx>
commit 5455f92b54e516995a9ca45bbf790d3629c27a93 upstream.
If ovl_check_origin() fails, we should put upperdentry. We have a reference
on it by now. So goto out_put_upper instead of out.
Fixes: a9d019573e88 ("ovl: lookup non-dir copy-up-origin by file handle")
