net/mlx5: fs, set non default device per namespace

Browse Source 
Add mlx5_fs_set_root_dev() function which swaps the root namespace
core device with another one for a given table_type.

It is intended for usage only by RDMA_TRANSPORT tables in case of LAG
configuration, to allow the creation of tables during LAG always
through the LAG master device, which is valid since during LAG the
master is allowed to manage the RDMA_TRANSPORT tables of its slaves.

In addition move the table_type enum to global include to allow its use
in a downstream patch in the RDMA driver.
