The ASA 5585-X high availability cluster will have no awareness of the failover event or failover state of the inline 3D8140 unless their failover causes a monitored interface link to go down on one of the ASAs.
If the 3D8140 is configured per best practice to fail-open on the network module's inline interface, this will never happen.
A true highest availability design would have interfaces from each ASA going to both inline IPS appliances. They could be in an Etherchannel or configured as redundant interfaces, depending on your throughput requirements and number of available interfaces.
