[PATCH rdma-next] RDMA/mlx5: Add missing check for return value in get namespace flow

[Leon Romanovsky]

From: Maor Gottlieb <maorg@nvidia.com>

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")
