[PACKET]: Fix skb->cb clobbering between aux and sockaddr
Both aux data and sockaddr tries to use the same buffer which
obviously doesn't work. We just happen to have 4 bytes free in
the skb->cb if you take away the maximum length of sockaddr_ll.
That's just enough to store the one piece of info from aux data
that we can't generate at recvmsg(2) time.
This is what the following patch does.
