[PATCH v5 2/2] net/mlx5: Fix memory leak in error path of ttc creation

[Henry Martin <bsdhenrymartin@gmail.com>]

Free ttc table memory when unsupported ttc_type is passed, to avoid
memory leak on the default error path in mlx5_create_inner_ttc_table()
and mlx5_create_ttc_table().

Fixes: 137f3d50ad2a ("net/mlx5: Support matching on l4_type for ttc_table")
