net/mlx5: fix ConnectX-4LX minimal inline data limit

Mellanox ConnectX-4LX NIC in configurations with disabled
E-Switch can operate without minimal required inline data
into Tx descriptor. There was the hardcoded limit set to
18B in PMD, fixed to be no limit (0B).

Fixes: 38b4b397a57d ("net/mlx5: add Tx configuration and setup")
