In roaming SC, shutdown standby SC to make another
takes STANDBY role. AMFD on standby was hung before
shutdown. So during the new node change to STANDBY,
it receives the AMFD up/down event from the old STANDBY
and it default set role to ACTIVE instead of the ACTIVE
already exist.
The fix is to ignore AMFD event on new standby.
