[B.A.T.M.A.N.] [PATCH maint 2/2] batman-adv: free skb on TVLV parsing success

[Antonio Quartulli]

From: Antonio Quartulli <anto...@open-mesh.com>

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 0b6aa0d43767889eeda43a132cf5e73df4e63bf2
