net/mlx5: Cancel delayed recovery work when unloading the driver
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')
