net/mlx5: Fix root flow table update

Browse Source 
When we destroy the last flow table we need to update
the root_ft to NULL.

It fixes an issue for when the last flow table is destroyed
and recreated again, root_ft pointer will not be updated,
as a result traffic will be dropped.

Fixes: 2cc43b494a6c ('net/mlx5_core: Managing root flow table')
