[PATCH mlx5-next 09/27] net/mlx5: Pass a namespace for packet reformat ID allocation

[Leon Romanovsky <leon@kernel.org>]

From: Mark Bloch <markb@mellanox.com>

Currently we attach packet reformat actions only to the FDB namespace.
In preparation to be able to use that for NIC steering, pass the actual
namespace as a parameter.
