[PATCH] common/mlx5: fix list unused lcore check

[PATCH] common/mlx5: fix list unused lcore check

[Suanming Mou]

While non-lcore list operations were supported, non-lcore index will
be converted to MLX5_LIST_NLCORE. In that case, no need to check the
lcore index be -1 or not anymore.

This commit removes the unused lcore check in list.
