    Always pass device_owner to _ipam_get_subnets()

    There was one code path where the existing device_owner
    value, which is used for subnet selection when service_type's
    are in use was not passed to _imap_get_subnets(). This could
    trigger one of two exceptions - HostNotCompatibleWithFixedIps()
    or IpAddressGenerationFailureNoMatchingSubnet() depending
    on the environment. Pass it along if known.

    Also update the IpAddressGenerationFailureNoMatchingSubnet
    exception to print the network_id and service_type values since
    it could aid in debugging the problem quicker.
