tcp: handle pure FIN case correctly
When skb->len==0, the recv_actor() returns 0 too, but we also use 0
for error conditions. This patch amends this by propagating the errors
to tcp_read_skb() so that we can distinguish skb->len==0 case from
error cases.
Fixes: 04919bed948d ("tcp: Introduce tcp_read_skb()")
