net/mlx5e: IPoIB, Use correct timestamp in child receive flow
[ Upstream commit 36e564b76f1862914ad32c35bab433e07da2ebf8 ]
The current implementation takes the child timestamp object from
the parent since the rq in mlx5i_complete_rx_cqe belongs to the parent.
This change fixes the issue by taking the correct timestamp.
Fixes: 7e7f4780c340 ("net/mlx5e: IPoIB, Use hash-table to map between QPN to child netdev")
