3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antonio Quartulli <antonio@xxxxxxxxxxxxx>
[ Upstream commit 05c3c8a636aa9ee35ce13f65afc5b665615cc786 ]
When the TVLV parsing routine succeed the skb is left
untouched thus leading to a memory leak.
Fix this by consuming the skb in case of success.
Introduced by ef26157747d42254453f6b3ac2bd8bd3c53339c3
