Log statement for updating info cache needs to be moved

[Aaron Rosen]

From the logs I notice that it says we are updating the info cache with None though that is not always true as if nw_info is not an instance of we NetworkInfo query neutron and then save that.

    Move log statement to expose actually info_cache value

    When debugging an info_cache issue I noticed the logs display:

    "Updating cache with info: None update_instance_cache_with_nw_info"

    Though we are not actually updating the info_cache with None as if
    nw_info is not isinstance(NetworkInfo we fetch the latest nw_info
    from neturon. This patch just moves the log statement so the actual
    value is exposed.
