net/mlx5e: Fix loopback self test when GRO is off
[ Upstream commit ef7a3518f7dd4f4cf5e5b5358c93d1eb78df28fb ]
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.
Fixes: 0952da791c97 ("net/mlx5e: Add support for loopback selftest")
