Subject: [PATCH] RDMA/mlx5: Add missing check for return value in get
namespace flow
[ Upstream commit c9776457bd5eaad4ce4ecb17af8d8f3cc6957c0b ]
Add missing check for return value when calling to
mlx5_ib_ft_type_to_namespace, even though it can't really fail in this
specific call.
Fixes: 52438be44112 ("RDMA/mlx5: Allow inserting a steering rule to the FDB")
