Remove reduntant call to update_instance_info_cache

get_instance_nw_info calls _get_instance_nw_info,
which is decorated with @refresh_cache. This in
turn calls update_instance_info_cache, again. This
is both expensive and more importantly dangerous because
the method update_instance_info_cache may call
_get_instance_nw_info itself, thus causing an infinite
loop.
