tcp: fix tcp_xmit_retransmit_queue() after rbtree introduction
I tried to hard avoiding a call to rb_first() (via tcp_rtx_queue_head)
in tcp_xmit_retransmit_queue(). But this was probably too bold.
Quoting Yuchung :
We might miss re-arming the RTO if tp->retransmit_skb_hint is not NULL.
This can happen when RACK marks the first packet lost again and resets
tp->retransmit_skb_hint for example (tcp_rack_mark_skb_lost())
Fixes: 75c119afe14f ("tcp: implement rb-tree based retransmit queue")
