cloudstack, cs_firewall: fix network not found error in return results (#2006)

Only a small issue in results.

In case of type is ingress, we rely on ip address, but in results we also return the network.
Resolving the ip address works without zone params. If the ip address is not located in the default zone and zone param is not set,
the network won't be found because default zone was used for the network query listing.

However since network param is not used for type ingress we skip the return of the network in results.
