Two SUs hosted on standby controller with 2N model. Recovery is 
node-switchover with su-failover flag enabled for SU1.

Steps to reproduce:
1)Bring attached configuration up. 
2) kill comp in SU1(active SU).

When AMFD gets recovery request for standby SC, it failovers SU1 and gives 
active to SU2 as a part of SU1 recovery. For SU2 recovery, it then sends 
quiesced assignment. This is a wrong sequence. Since SU2 is hosted on failed 
node, AMFD should not failover SU1 to SU2,

>From code perpective: AMFD marks all SUs of failed node OOS only in INIT_DONE 
>state. In APP_STATE this needs to be done by respective reocovery funtion. In 
>case of node-failvoer recovery avd_node_down_appl_susi_failover() is marking 
>SUs OOS before performing failover. But perform_nodeswitchover_recovery() is 
>not marking all the SUs OOS before performing failover/switchover of any SU.
