[PATCH 1/9] net/mlx5/hws: skip RTE item when inserting rules by index

[Itamar Gozlan]

The location of indexed rules is determined by the index, not the item
hash. A matcher test is added to prevent access to non-existent items.
This avoids unnecessary processing and potential segmentation faults.

Fixes: 405242c ("net/mlx5/hws: add rule object")
