Subject: [PATCH rdma-next 1/7] RDMA/mlx5: Delete not-available udata check

XRC_TGT QPs are created through kernel verbs and don't have udata at all.

Fixes: 6eefa839c4dd ("RDMA/mlx5: Protect from kernel crash if XRC_TGT doesn't have udata")
Fixes: e383085c2425 ("RDMA/mlx5: Set ECE options during QP create")
