ml2 update_network/subnet returning stale info

[Kevin Benton]

update_network and update_subnet need similar fixes as the one for bug 1625981. if an extension makes a change, the revision number bump is not reflected in the update result

This can be seen by updating the dns_domain on a network with the dns extension. The update result will not have a bumped revision number even though the revision number was incremented.

    Refetch subnet/network from DB in ML2 update ops

    This ensures that any extensions run in the ML2 extension framework
    that bump the revision number of the subnet or network result in the
    altered revision number being returned to the API caller and passed
    into the ML2 mech drivers and callback handlers.
