Just back from vacation.
In my test, the comp-failover was not reported to AMFD because the escalation
timer has expired just before the return of clc cleanup. Also I have tried to
add more PI components, and only one of them does saAmfFinalize, the issue
still happens since the assignment sequence seems to be discontinued due to the
errorneous component.

The admin command shutdown node (or nodegroup) will hang if component calls
saAmfFinalize during component failover. Trace is attached.
Scenario:
. Issue admin shutdown node
. component rejects quiescing assignment
saAmfCSIQuiescingComplete(SA_AIS_ERR_FAILED_OPERATION)
. component calls saAmfFinalize, finalizing handle
. Due to failure of quiescing assignment, component failover recovery is
started. As result of it, clc cleanup is called.
. The event finalize handle comes before clc cleanup returns ok.
. avnd_comp_clc_terming_cleansucc_hdler() is handling cleanup success case. The
quiescing sequence can't be continued because
avnd_comp_cmplete_all_assignment() currently seems to handle normal case, which
is callback list exist. But the fact component is unregistered, all handles are
deleted by saAmfFinalize. No su_si_oper_done is sent to amfd at the end, thus
the command hang until timeout
Another similiar test is done on amf_demo, which calls saAmfFinalize when
component receives sigterm. The assignment is quiesced then removed
successfully, since amfnd is "aware of " unregistered component during quiesced
assignment sequence.
The quiescing assignment sequence should be aware of unregistered component
this case, in order to avoid hanging shutdown node. Or saAmfFinalize should
return TRY_AGAIN, to be analyzing ...
