4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eli Cohen <eli@xxxxxxxxxxxx>
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.
Fixes: e126ba97dba9 ('mlx5: Add driver for Mellanox Connect-IB adapters')
