Subject: RDMA/mlx5: Fix check for supported user flags when creating a QP
Patch-mainline: v5.0-rc5
Git-commit: 8af526e035357d2df1d7cacc51bcde0a5d9f9f9f
References: bsc#1103991 FATE#326007
When the flags verification was added two flags were missed from the
check:
* MLX5_QP_FLAG_TIR_ALLOW_SELF_LB_UC
* MLX5_QP_FLAG_TIR_ALLOW_SELF_LB_MC
This causes user applications that were using these flags to break.
Fixes: 2e43bb31b8df ("IB/mlx5: Verify that driver supports user flags")
