net: packet: use sockaddr_ll fields as storage for skb original length in recvmsg path
As part of an effort to move skb->dropcount to skb->cb[], 4 bytes of additional room are needed in skb->cb[] in packet sockets. Store the skb original length in the first two fields of sockaddr_ll (sll_family and sll_protocol) as they can be derived from the skb when needed.
