net/mlx5: Fix condition for termination table cleanup
When we destroy rules from slow path we need to avoid destroying termination tables since termination tables are never created in slow path. By doing so we avoid destroying the termination table created for the slow path. Fixes: d8a2034f152a ("net/mlx5: Don't use termination tables in slow path") Signed-off-by: Eli Cohen <eli@mellanox.com> Reviewed-by: Oz Shlomo <ozsh@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
