This bug arrived with this commit:
MEDIUM: quic: Ack delay implementation
It is possible that the idle timer task was already in the run queue when its
->expire field was updated calling qc_idle_timer_do_rearm(). To prevent this
task from running in this condition, one must check its ->expire field value
with this condition to run the task if its timer has really expired:
!tick_is_expired(t->expire, now_ms)
Furthermore, as this task may be directly woken up with a call to task_wakeup()
all, for instance by qc_kill_conn() to kill the connection, one must check this
task has really been woken up when it was in the wait queue and not by a direct
call to task_wakeup() thanks to this test:
(state & TASK_WOKEN_ANY) == TASK_WOKEN_TIMER
Again, when this condition is not fulfilled, the task must be run.
Must be backported where the commit mentionned above was backported.
