net/mlx5: Use underlay QPN from the root name space
Root flow table is dynamically changed by the underlying flow steering
layer, and IPoIB/ULPs have no idea what will be the root flow table in
the future, hence we need a dynamic infrastructure to move Underlay QPs
with the root flow table.
Fixes: b3ba51498bdd ("net/mlx5: Refactor create flow table method to accept underlay QP")
