batman-adv: always reply batman icmp packets with primary mac
When receiving an batman icmp echo request or in case of a time-to-live
exceeded batman would reply with the mac address of the outgoing
interface which might be a secondary interface. Because secondary
interfaces are not globally known this might lead to confusion.
Now, replies are sent with the mac address of the primary interface.

batman-adv: fix batman icmp originating from secondary interface
If a batman icmp packet had to be routed over a secondary interface
at the first hop, the mac address of that secondary interface would
be written in the 'orig' field of the icmp packet. A node which is
more than one hop away is not aware of the mac address because
secondary interfaces are not flooded through the whole mesh and
therefore can't send a reply.
This patch always sends the mac address of the primary interface
in the 'orig' field of the icmp packet.

batman-adv: Directly prepare icmp packets in socket buffer
It is unnecessary to generate an icmp packet in an extra memory region
and than copying it to a new allocated skb.
This also resolved the problem that we do inform the user that we
couldn't send the packet because we couldn't allocate the socket buffer.
