macvlan: Fix leaking skb in source mode with nodst option
The MACVLAN receive handler clones skbs to all matching source MACVLAN interfaces, before it passes the packet along to match on destination based MACVLANs. When using the MACVLAN nodst mode, passing the packet to destination based MACVLANs is omitted and the handler returns with RX_HANDLER_CONSUMED. However, the passed skb is not freed, leaking for any packet processed with the nodst option. Properly free the skb when consuming packets to fix that leak.
