WARNING: possible recursive locking detected

--------------------------------------------
syz-executor.3/10308 is trying to acquire lock:
ffff88807958cd00 (team->team_lock_key#5){+.+.}-{3:3}, at: team_port_change_check+0x51/0x1e0 drivers/net/team/team.c:3010

but task is already holding lock:
ffff88807958cd00 (team->team_lock_key#5){+.+.}-{3:3}, at: team_add_slave+0xab/0x2760 drivers/net/team/team.c:1986

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

       CPU0
       ----
  lock(team->team_lock_key#5);
  lock(team->team_lock_key#5);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
