[dpdk-stable] [PATCH v2 09/67] net/mlx5: warn for unsuccessful memory registration

[Yongseok Koh]

From: Shahaf Shuler <shahafs at mellanox.com>

[ upstream commit bb6883120a95861c1d4dae27839871ce5805e381 ]

Memory registration can fail, add the proper warning for such scenario
for it at least to be visible in debug mode.
