PAN-5925 898112

Fixed an issue on firewalls in an HA active/active configuration where session timeouts for some traffic were unexpectedly refreshed after a commit or HA sync attempt. However, in PAN-OS 7.1.4, this issue is fixed only for an HA pair where both peers are running a PAN-OS 7.1 release; this issue is not fixed in a configuration where one firewall is running a PAN-OS 7.1 release and the other is running a PAN-OS 7.0 or earlier release.
