[dpdk-dev] [PATCH 1/5] net/mlx5: fix unused calculation in RSS expansion

The RSS flow expansion get a memory buffer to fill the new patterns of
the expanded flows.
This memory management saves the next address to write into the buffer
in a dedicated variable.

The calculation for the next address was wrongly also done when all the
patterns were ready.

Remove it.
