amf: fix unexpected node reboot during failover [#3308]
During SC failover, message sent on ACTIVE AMFD can not be
checked point to AMFD on STANDBY SC. But the AMFND still
increase receive/send msg id count. Then STANDBY SC takes
ACTIVE and mismatch message id b/w AMFND and new active AMFD.
Solution is to make msg id count alignment b/w AMFD/AMFND
in this case.
