PR10651 / RHBZ653286: mod_timer vs. del_timer_sync races
It appears possible for del_timer_sync (from outside) and mod_timer
(from within a timer callback) to race. Defeat this race by ensuring
that the timer callback checks an atomic_t flag before rescheduling
itself with mod_timer.
* runtime/transport/relay_v2.c (transport_state): Turn into an atomic_t.
Update users.
(__stp_relay_wakeup_timer): Observe flag.
(_stp_transport_data_fs_{start,stop}): Update flag before timer manipulations.
* runtime/transport/ring_buffer.c: Ditto for corresponding functions.
