John Fastabend 7ebc14d507 bpf: sockmap, consume_skb in close path 
Currently, when a sock is closed and the bpf_tcp_close() callback is
used we remove memory but do not free the skb. Call consume_skb() if
the skb is attached to the buffer.

Fixes: 1aa12bdf1b ("bpf: sockmap, add sock close() hook to remove socks")
