net/mlx5e: Do not re-apply TIR loopback configuration if not necessary

On old firmware, (tis_tir_td_order=0), TIR of a transport domain should
either be created after all SQs of the same domain, or TIR.self_lb_en
should be reapplied using MODIFY_TIR, for self loopback filtering to
function correctly.

This is not necessary anymnore on new FW (tis_tir_td_order=1), thus
there's no need for calling modify_tir operations after creating a new
set of SQs to maintain the self loopback prevention functional.

Skip these operations.

This saves O(max_num_channels) MODIFY_TIR firmware commands in
operations like interface up or channels configuration change.
