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 ...
