Subject: IB/mlx5: Fix fatal error dispatching

From: Eli Cohen <[email protected]>

commit dbaaff2a2caa03d472b5cc53a3fbfd415c97dc26 upstream.

When an internal error condition is detected, make sure to set the device inactive after dispatching the event so ULPs can get a notification of this event.
