Notice: Undefined variable: items on template

I see this issue before but it's closed and it's on a different template.

Notice: Undefined variable: items in include() (line 19 of ../modules/contrib/fences/templates/field--fences-div.tpl.php).
Warning: Invalid argument supplied for foreach() in include() (line 19 of ../modules/contrib/fences/templates/field--fences-div.tpl.php).

It's required wrap the loop on isset to check if this value is set.

I leave one patch to fix this.
