net/mlx5e: Fix loopback self test when GRO is off

Browse source

[ Upstream commit ef7a3518f7 ]

When GRO is off, the transport header pointer in sk_buff is
initialized to network's header.

To find the udp header, instead of using udp_hdr() which assumes
skb_network_header was set, manually calculate the udp header offset.
