[PATCH 1/4] net/mlx5/hws: fix direct index insert on dep wqe

[Dariusz Sosnowski <dsosnowski@nvidia.com>]

From: Alex Vesker <valex@nvidia.com>

In case a depend WQE was required and direct index was
needed we would not set the direct index on the dep_wqe.
This leads to incorrect insertion to index zero.

Fixes: 38b5bf6452a6 ("net/mlx5/hws: support insert/distribute RTC properties")
