net/mlx5e: Allow setting self loopback prevention bits on TIR init

Browse Source 
Until now, IPoIB was creating TIRs without setting self loopback
prevention, then modifying them in activation stage.

This is a preparation patch, that will be used by IPoIB to init TIRs
properly without the need for following calls of modify_tir.
