IB/mlx5: Add ability to hash by IPSEC_SPI when creating a TIR

When a Raw Ethernet QP is created, we actually create a few objects.
One of these objects is a TIR. Currently, a TIR could hash (and spread
the traffic) by IP or port only. Adding a hashing by IPSec SPI to TIR
creation with the required UAPI bit.
