[dpdk-dev] [PATCH] net/mlx5: fix debug variable initialization

[Gregory Etelson <getelson@nvidia.com>]

Use `__rte_unused` macro to mask a debug variable instead of `#ifdef`.
This way, if the variable is used in a macro, it does not depend on
how the macro is expanded.

Fixes: 91f0e029ce5f ("net/mlx5: translate flex item pattern into matcher")
