Can you add it as a selftest under selftests/drivers/net/team/?

Stan, this "fix" may work for the promisc flag but won't we have 
the same problem with sync'ing the address list? Looks like team
will do:
 - team_set_rx_mode()
   - dev_uc_sync_multiple()
     - __dev_set_rx_mode(port->dev)
so AFAICT we're calling ndo_set_rx_mode without holding the instance
lock?
