[PATCH 26/30] net/mlx5/hws: fix potential wrong errno value

[Gregory Etelson]

From: Rongwei Liu <rongw...@nvidia.com>

A valid rte_errno is desired when DR layer api returns error
and it can't over-write the value set by under-layer.

Fixes: df61fcd5f3ca ("net/mlx5/hws: support insert header action")
