net/mlx5: fix Tx inline minimum for ConnectX-5

The function mlx5_set_min_inline() includes a switch() that checks
various PCI device IDs in order to set the txq_inline_min value.  No
value is set when the PCI device ID matches the ConnectX-5 adapters,
resulting in an assert() failure later in the function
mlx5_set_txlimit_params().

This error was encountered on an IBM Power 9 system running RHEL 7.6
w/o Mellanox OFED installed.

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