IB/mlx4: Follow mirror sequence of device add during device removal
[ Upstream commit 89f988d93c62384758b19323c886db917a80c371 ] Current code device add sequence is: ib_register_device() ib_mad_init() init_sriov_init() register_netdev_notifier() Therefore, the remove sequence should be, unregister_netdev_notifier() close_sriov() mad_cleanup() ib_unregister_device() However it is not above. Hence, make do above remove sequence.
