    amf: fix Comp stuck in RESTARTING presence state [#3011]
    
    During SU (many COMPs) restart recovery, if any COMP finish instantiated
    then crash while other COMPs are still instantiating, AMF recovery it by
    restarting but AMF only cleanup without re-instantiation because AMF see
    the COMP is not eligible for instantiation. The error COMP is stuck in
    RESTARTING without further action from AMF.
    
    AMF should allow COMP re-instantiation if SU state is INSTANTIATING and
    error COMP state is RESTARTING.

** [tickets:#3011] amf: comp stuck in RESTARTING presence state**

**Status:** fixed

When a SU (has many comp) is instantatiating for SU restart recovery, some comp 
are instantiated then crash, AMF recovery them by restarting but AMF only 
cleanup without re-instantiation them because AMF see them are not eligible for 
instantiation.
~~~
   if (isRestartSet(comp->su)) {  // SU is restarting (RESTART admin op or
                                  // recovery policy).
     if (isFailed(comp->su)) {  // SU is failed (case surestart recovery).
       /*During surestart recovery, after cleanup of all components, amfnd 
starts
         instantiation of components. A component may fault at this stage. Such 
a
         component is eligible for instantiation.*/
                    if ((comp->pres == SA_AMF_PRESENCE_INSTANTIATING) &&
                               (comp->su->pres == 
SA_AMF_PRESENCE_INSTANTIATING))
         return true;

~~~
These comp are stuck in RESTATING presence state without further action from 
AMF.
