net/mlx5: IPoIB, set self loopback prevention in TIR init

In IPoIB, the self loopback prevention configuration apply in activation
stage has two roles: fulfill a firmware requirement for old firmware
(tis_tir_td_order=0), and update the proper configuration as it was not
set in init.

Here we set the proper configuration in init, to allow skipping the
modify_tirs commands on new firmware in a downstream patch.
