Matthieu Baerts (NGI0) c6877abcdb mptcp: pm: send ACK on an active subflow 
commit c07cc3ed89 upstream.

Taking the first one on the list doesn't work in some cases, e.g. if the
initial subflow is being removed. Pick another one instead of not
sending anything.

Fixes: 84dfe3677a ("mptcp: send out dedicated ADD_ADDR packet")

[ Conflicts in pm_netlink.c, because the code has been refactored in
  commit f5360e9b31 ("mptcp: introduce and use mptcp_pm_send_ack()")
  which is difficult to backport in this version. The same adaptations
  have been applied: iterating over all subflows, and send the ACK on
  the first active subflow. ]
