If an interface enslaved into batman-adv is a bridge (or a virtual interface built on top of a bridge) the nf_bridge member of the skbs reaching the soft-interface is filled with the state about "netfilter bridge" operations.
Then, if one of such skbs is locally delivered, the nf_bridge member should be cleaned up to avoid that the old state could mess up with other "netfilter bridge" operations when entering a second bridge. This is needed because batman-adv is an encapsulation protocol.
However at the moment skb->nf_bridge is not released at all leading to bogus "netfilter bridge" behaviours.
Fix this by cleaning the netfilter state of the skb before it gets delivered to the upper layer in interface_rx().
