net/mlx5: fix order of items in NEON scatter

Previous patch added handling of metadata for multi-segment packet.
Function txq_scatter_v in file mlx5_rxtx_vec_neon.h was updated
incorrectly, items were inserted into WQE in wrong order.

This patch fixes the issue, inserting items into WQE correctly.
