net/mlx4_core: Raise slave shutdown event upon FLR
There might be cases that PF doesn't get a "reset" command upon slave down (e.g. virsh destroy). In these cases, however, an FLR event is issued. Therefore, when the PF receives an FLR event for a slave, it should also generate a shutdown event on the PF for that slave, to let the PF upper layers (mlx4_ib, eth) perform any required cleanup/actions associated with slave shutdown.
