Subject: [PATCH] net/mlx5: fix tunnel offload detection

[ upstream commit 772d34356d72af2f5a3d483c83afb00d4cb4ae03 ]

PMD driver got random tunnel_en value on ConnextX-4LX NIC, depends on
compile optimization level. The variable was not initialized and
detection logic was absent.

Fixes: f5fde5205101 ("net/mlx5: add hardware checksum offload for tunnel packets")
