Replace timer lock with SMR
The lock was not used to protect any data structures, it was purely to
ensure race-free setting of t_disabled. That is, that no other thread
was halfway through any wg_timers_run_* function. With smr_* we can
ensure this is still the case by calling smr_barrier() after setting
t_disabled.
