A simple start up sequence after headless as in 2162.seq, 3 major cases that
SC-1 can down from start up till headless recovery:
1- SC1 goes down before SC2 is successfully indicated as standby controller,
which happens before standby assignment for 2N Opensaf SU
2- SC2 is standby controller, SC1 goes down before SC2 complete cold sync
3- SC2 completes cold sync, SC1 goes down before cluster initiation is
done/timeout
If case 2 happens, SC2 is rebooted as expected result today
Case 1 is reproduced, see attached file c1.tgz, the result is that SC2 gets
stuck in receiving node_up msg from all nodes, the cause is 2N Opensaf SU in
SC2 could not be assigned as active
Case 3 is primarily reported in this ticket.

** [tickets:#2162] AMF: Headless recovery failed if SC failover during headless
sync**
**Status:** assigned
**Milestone:** 5.2.FC

Test steps:
- Set up 2N assignment, PL4 hosts SU4 (active assignment), PL5 host SU5
(standby assignment)
- Stop SCs
- Stop PL4
- Restart SC1
- Restart SC2
- Since PL4 is stopped, headless sync will be time out in 10 secs. During this
10 secs, reboot SC1 to trigger SC failover
Observation: SC2 becomes active controller, cold sync complete, but SU5 still
has standby assignment.
When SC2 becomes active controller, the part of code that performs headless
recovery is not executed (function failover_absent_assignment()). Therefore,
the transient assignments remain after SC failover.
Log/trace are attached.
