The re-application of self loopback prevention attributes in TIRs is
necessary in old firmwares (where tis_tir_td_order cap is cleared) after
recreation of SQs.

However, this is not needed in new firmware with tis_tir_td_order=1.

As a preparation patch, enhance the function structures to differentiate
between an explicit loopback prevention configuration apply, and the
re-apply operation required by old firmware.

Loopback selftests should now call mlx5e_modify_tirs_lb() directly, as
their use case is not related to the firmware limitation.
