[PATCH rdma-rc 09/12] IB/mlx5: Fix fatal error dispatching

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Eli Cohen <eli-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

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.

Fixes: e126ba97dba9 ('mlx5: Add driver for Mellanox Connect-IB adapters')
