amf: reboot to recovery PL in split-brain [#3309]
The connection between the standby SC and that PL was dropped
(disconnect the reconnect ), but that PL still connected with
the active SC. It led the standby SC considered that PL absented
regardless the connection was established after that. During failover,
the standby SC will notify all recorded absent nodes left cluster.
It causes PL left cluster from AMF view but still connect to active.
This scenario is a kind of split-brain use case and amfd should order
PL reboot to recovery the issue.
