[dpdk-dev] [PATCH 1/3] net/mlx5: fix unsupported offloads disablement

mlx5 offloads which are unsupported on Windows
are currently disabled by checks with IBV/DV flags
which are irrelevant to Windows.

The checks are removed until they are fully available.

Fixes: 93f4ece91a1f ("net/mlx5: spawn ethdev ports on Windows")
