rv: Fix read_lock scope in per-task DA cleanup

Browse source

The da_monitor_reset_all() function for per-task monitors takes
tasklist_lock while iterating over tasks, then keeps it also while
iterating over idle tasks (one per CPU). The latter is not necessary
since the lock needs to guard only for_each_process_thread().

Use a scoped_guard for more compact syntax and adjust the scope only
where the lock is necessary.
