[dpdk-stable] [PATCH v2 42/67] net/mlx5: remove 32-bit support

[Yongseok Koh]

From: Nélio Laranjeiro <nelio.laranjeiro at 6wind.com>

[ upstream commit ebbb81eb27daca0a89ee8f228fcf141d9eb6ef1c ]

naddr variable was introduced in
commit 9a7fa9f76d9e ("net/mlx5: use vector types to speed up processing")
to avoid compilation errors on 32bits compilation, as x86_32 is no more
supported by rdma-core nor by MLNX_OFED, this variable becomes useless and
can be safely removed.
