RDMA/mlx5: Delete not-available udata check

[ Upstream commit 5f6bb7e32283b8e3339b7adc00638234ac199cc4 ]

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")
