net/mlx5: Lag, Add single RDMA device in multiport mode
In MultiPort E-Switch mode a single RDMA is created. This device has multiple
RDMA ports that represent the uplink ports that are connected to the E-Switch.
Account for this when creating the RDMA device so it has an additional port for
the non native uplink.
As a side effect of this patch, use shared fdb in multiport eswitch mode.
