syz.0.2975/12168 is trying to acquire lock:

but task is already holding lock:

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(team->team_lock_key#2);
  lock(team->team_lock_key#2);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
