Unlike other parts of the mlx4_ib code, the function build_mlx_header() doesn't check if the iboe netdev of the given port is valid before dereferencing it, which can cause a crash if the ethernet interface has already been taken down. Fix this by checking for a valid netdev pointer before using it to get the port MAC address.
