Olivier Houchard 261aa23522 BUG/MEDIUM: tasks: Do not loop in task_schedule() if a task is running
Commit 7e1cc0fcdb made it so we'd loop in
task_schedule() if the task is currently running, so that we'd be sure
that the task would not overwrite the expire field. However,
task_schedule() may be called while a lock is held, and if the running
task attempts to acquire that lock, it will lead to a deadlock.
So instead, if the task is running, just wake it up, so that we're sure
that it will reschedule itself correctly, as it should do anyway. We
already do nothing if the task is in a run queue, so it is expected that
tasks do that, and if they do not, then it is a bug.

This should fix github issue #3350
This should be backported where 7e1cc0fcdb
has been backported, which should be up to 2.8.
