Fix cherry-pick check for merge patch

Cherry-pick check script validates the proposed patch's commit message.
If a patch is not on top of the given branch then Zuul rebases it to
the top and the patch becomes a merge patch. In this case the script
validates the merge patch's commit message instead of the original
patch's commit message and fails.

This fix selects the parent of the patch if it is a merge patch.
