net/mlx5: fix parameters defaults

net/mlx5: fix parameters defaults

With the Enhanced multi packet send addition, the defaults were made
in order to get the maximum out of the box performance.
Features like tso, don't use the enhanced send, however the defaults
are still valid. This cause Tx queue creation to fail.

Fixes: 3f13f8c23a7c ("net/mlx5: support hardware TSO")
Fixes: 6ce84bd88919 ("net/mlx5: add enhanced multi-packet send for ConnectX-5")
