net/mlx5: Cancel delayed recovery work when unloading the driver
commit 2a0165a034ac024b60cca49c61e46f4afa2e4d98 upstream. Draining the health workqueue will ignore future health works including the one that report hardware failure and thus we can't enter error state Instead cancel the recovery flow and make sure only recovery flow won't be scheduled. Fixes: 5e44fca50470 ('net/mlx5: Only cancel recovery work when cleaning up device') Signed-off-by: Mohamad Haj Yahia <mohamad@mellanox.com> Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
