net/mlx5e: SHAMPO, reduce TIR indication
[ Upstream commit 99a2b9be077ae3a5d97fbf5f7782e0f2e9812978 ]
SHAMPO is an RQ / WQ feature, an indication was added to the TIR in the
first place to enforce suitability between connected TIR and RQ, this
enforcement does not exist in current the Firmware implementation and was
redundant in the first place.
