padata: free correct variable

BugLink: http://bugs.launchpad.net/bugs/1692900
commit 07a77929ba672d93642a56dc2255dd21e6e2290b upstream.

The author meant to free the variable that was just allocated, instead
of the one that failed to be allocated, but made a simple typo. This
patch rectifies that.
