Subject: RDMA/mlx5: Use the correct obj_id upon DEVX TIR creation
Patch-mainline: v5.12-rc1
Git-commit: 8798e4ad0abe0ba1221928a46561981c510be0c6
References: bsc#1103991 FATE#326007
Use the correct obj_id upon DEVX TIR creation by strictly taking the tirn
24 bits and not the general obj_id which is 32 bits.
Fixes: 7efce3691d33 ("IB/mlx5: Add obj create and destroy functionality")
