This reverts commit fbdd0049d98d44914fc57d4b91f867f4996c787b.

Due to commit in fixes tag, netdevice events were received only
in one net namespace of mlx5_core_dev. Due to this when netdevice
events arrive in net namespace other than net namespace of mlx5_core_dev,
they are missed.

This results in empty GID table due to RDMA device being detached from
its net device.

Hence, revert back to receive netdevice events in all net namespaces to
restore back RDMA functionality in non init_net net namespace.
